Software testing is an important aspect of the software development lifecycle. Without proper testing of a product, it is difficult to identify if it is meeting the requirements that have led to its design and development. Also, a product cannot be launched in the market without testing. With software testing training you come to know that there are different methods of software testing that can be adopted. Let’s see here the various methods of testing.

Black-Box Testing:

The method of testing where it is done without having any knowledge about the internal mechanisms of the application is called black-box testing. In this type of testing, the tester is unaware of the system architecture and does not know the program code. In this method, the testers work at the user interface level and check only the outputs by providing inputs. This method is also called functional or specification-based testing. The main advantage of this method of testing is that it clearly separates user’s perspective from that of the developer’s and it is suitable for large code products. It has a disadvantage also because the tester cannot identify error-prone areas as there is no code access.

White-Box Testing:

As a contrast to the black-box testing, white-box testing is the thorough examination of the internal logic and structure of the code. It is also called glass testing or open-box testing. As discussed, to perform testing in this method, a tester has to have access to the code of the program. Tester has to find out that part or unit of the program code which is not working properly and has bugs. Usually, the software developers only do this kind of testing. This method helps in optimizing the code.

Grey-box testing:

Grey-box testing is a testing method wherein the tester has limited access to the code and has limited knowledge of the internal mechanism of the program. This method offers the combined benefits of black-box and white-box testing. In this kind of testing, the testing is performed from the perspective of a user and not the designer.

Static Testing:

In the method of static testing, the code and documentation are examined but the program is not executed. It is done in the early stages of product development during the verification process.

Dynamic Testing:

In the method of dynamic testing, the software product is executed with a number of inputs to compare the outputs with the expected behavior.

Whatever the method of testing is, the result expected is identifying the bugs in the product and minimizing the deviations from the expected behavior.

Softwaretesting is the examination or investigation conducted to check the quality of a software product or service. According to estimates, global software testing services market is expected to grow around a CAGR of 11% in the period of 2016-2020. It is also one of the top careers in demand in recent years. However, for someone who wants to join this career, there is a little ambiguity owing to certain myths. Let us take a look at some of these myths and realities related to the softwaretesting.

1. Testing is boring: The misconception about software testing is that it is a boring job and is mundane. However, the reality is that testing is not a repetitive work and it requires the skill of a detective to identify the bugs in software. With software testing training one can understand that it offers a new challenge every day and gives plenty of opportunities to explore and learn new things on a regular basis.

2. Testing doesn’t require coding skills: One of the most common myths about testing is that it doesn’t require good coding skills, so one with weak coding skills gets into the testing career. This is absolutely false. In reality, testing too requires coding and depending on how complex the project under evaluation is a software tester may require writing a code that is more complex than what a developer writes.

3. Testing is easy and anyone can do it: People have a common notion that testing is an easy job of finding bugs. However, with software testing training one gets to know that testing is not restricted to identifying bugs but it requires the tester to have a good understanding of the complete product architecture and how it will be used by the end-user. Software testers need to possess a different skill set with a combination of Java, C, Ruby, Python etc. and profound knowledge of the software manuals and automation tools.

4. Testers are paid less and do not get fame: It is a complete myth that testers are paid less and do not get fame. In reality, testers are very important for an organization as no organization wants to compromise on the quality of the product which has a direct and significant impact on the product and brand reputation. Hence, efficient and expert testers get a pay package that is more than that of an equally experienced developer.

5. Testers have a job only at the end of the project lifecycle: Many people wrongly think that the job of a tester is only post development in the project life cycle. However, if this is the reality, the project gets stuck with big problems. Testers also need as much time as developers need to understand the needs of the stakeholders and conduct tests. So, this has to be a continuous process right from the initiation of the project.

Software testing is for those who like to explore and discover the flaws in software which is an amazing job to do. Learn the nuances of testing with the best software testing training inHyderabad provided by Ikya Global.

How Different are Verification and Validation in Software Testing ~ Ikya Global EDU

Picture courtesy: www.differencebtw.com

Creation of software involves various stages like planning, developing and testing the final product.  Software testing is that crucial process in the software development which ensures that the final product is in line with the original plan and also meets the customer and industry standards. Software testing professionals are in great demand and there are numerous software testing traininginstitutes in Hyderabad that help you become a professional.

If you are developing software, how will you know if you have built the right system and built the system right? This is possible with the two processes of software testing – verification and validation. Usually, it is thought that verification and validation both are one and the same. Many people use these two terms interchangeably. However, in the testing field, these two terms mean different things. If you want to become a software tester and go for a course in software testing training, then you should be interested to know the difference between verification and validation.

Verification:

Verification is a process that helps in determining if the finished product of a particular phase in the development life-cycle is meeting the requirements that have been specified at the beginning of the phase.

·         It is to ascertain if the right system has been built.

·      The main objective of this process is to ensure that the software meets the requirements specified by the customers.

·         It is related to the evaluation of the final product to see if satisfies the business needs.

·         It is done with the execution of the software.

·         This involves dynamic testing techniques like validating and testing the actual code.

·         It uses methods like black box testing, gray box testing etc.

·         It is the process carried out after verification.

Just to put in plain words, verification is to check if outputs are according to the inputs and validation is to check if the software is accepted by the end-user or not. This can be understood well practically with proper software testing training. Ikya Global is one of the best software testingtraining institutes in Hyderabad where you gain practical knowledge with real-time company assignments.

For any company that creates software, it is a big task to see that it does not have any bugs that diminish the software quality or make it unfit for use. This task is taken care of by professionals who are skilled in software testing. Software testing includes the techniques and procedures that facilitate the identification of software bugs and verifying if the software is fit for use.

Software bugs:

When a programmer creates software, errors or mistakes may happen while designing and building the software. These errors or mistakes are the defects or bugs in the software. In simple words, a software bug is an error or defect in a software program that results in an unexpected or incorrect outcome or causes to work in a way that is unintended of the program. A program with many bugs or bugs that severely impact the program’s functionality is called buggy or defective. Software testing professionals known as software testers are people who do the job of finding bugs in a software program or write codes that support testing.

Reasons for software bugs:

As part of software testing bugs are identified, but identifying bugs is not an easy task, though after finding it out correcting is easier. It is easier to find out the bugs and rectify them if the reasons why software has bugs are known. Software testing training helps in understanding these reasons and rectifying them. Here is a list of the common reasons why software has bugs.

1.     Improper communication – Lack of proper communication between stakeholders, software development team and software testing team is one of the major reasons for defects in software. Improper communication may be in the form of unclear requirements or interpreting the requirements in a wrong way.
2.       Manual errors - It is common for humans to make mistakes. Programmers are also humans and like all humans, they too can make mistakes. Lack of domain knowledge and inexperience in coding practices along with missing unit testing are reasons for some defects.
3.     Changes in requirements – Due to many circumstances, a customer may ask for changes or modifications in the current design or project that requires a lot of changes to be made to the project that is completed. Such changes and modifications may result in defects in the program as many dependencies among parts of the project get impacted and it is difficult to keep a track of all the changes being made.
4.      Time constraints – Errors and mistakes are more likely when the deadlines are tight. If proper and sufficient time is not available for designing, coding and testing, the software is obviously prone to defects.

With so many reasons that bring flaws to a software program, it becomes all the more important to implement software testing without failure so as to minimize the bugs and their impact on the software performance. Hence, software companies are in need of software testers. To become a software tester, join Ikya Global that provides a comprehensive program in software testing training in Hyderabad.

Software Testing and Its Importance ~ Ikya Global EDU

With the ever-growing importance and use of the internet throughout the world, companies are creating new software very often. The users also want products that are better than previous ones that are updated and are user-friendly. Taking into consideration the customers choices and preferences companies are bringing out software releases with newer features and added capabilities. But, any product that is new has to be tested if it is working as planned and is not defective with bugs. Releasing software that is defective with bugs affects the user experience and creates a negative impact on the company’s brand image.

What is software testing?

Software testing is the scrutiny of the quality of the software product or service to provide information to the stakeholders of the product or service. It provides objective and independent analysis of the software quality and the risks associated with its failure to the stakeholders. It includes techniques and procedures that help in identifying the software bugs and reviewing if the software is fit for use. In other words, it is the process of verifying if the software satisfies the following:

• Meets the business and technical specifications that have influenced the product design and development
• Responds appropriately to all the inputs
• Performs the functions expected within specified time
• Easy to install and run in the intended environment
• Is user-friendly     

          Importance: 

       

         As with all other evaluations, software testing also is important, because everyone makes mistakes  and some mistakes may get costly for companies. Since we cannot identify our own mistakes,

  someone else has to identify our mistakes and help us to rectify them. The importance of software testing can be noted as below-

   

  ü  To identify defects and errors those were made during the various software development lifecycle phases.

  ü  To gain customer’s trust and satisfaction in the product and company

  ü  To provide a high-quality product with features that require minimal maintenance costs and give results that are accurate and reliable.

  ü  To stay in the business as failure of a product or service is very expensive for future endeavors

Being a Professional in Software Testing

Software testing professionals execute an application or software program to find bugs. They validate and verify that a specificprogram or application meets the technical and business requirements that guided its development and design. Software testing courses thusinvolveteaching the evaluation of properties of interest in a system or software component that indicate the extent to which it responds correctly to all inputs, is sufficiently usable, performs function in an acceptable time limit and can be installed and run in intended environments.

Testing helps prevent unexpected results of an application and helps improve its long-term maintenance.  Testing methodologies vary with the purpose of testing and the requirements of the software. There are different types of testing which include Acceptance Testing, Beta Testing, Functional Testing, Integration Testing, Performance Testing, Regression Testing, Stress Testing,             System Testing, Unit Testing and Usability Testing.

Skills for Being a Software Tester

In order to be a good software tester, one needs to develop the necessary skills through credible software testing training. To be an efficient professional in software testing, one needs to have sharp analytical skills that help him break up the software system into smaller components to better understand and test it. Strong technical skills are also a must in this field. Software testers need to have a high proficiency in Open Office, MS Office, QTP and testing tools and also need to develop a deep understanding of the software system under test. Software testers should also have good written and verbal communication skills, the ability to stay productive despite a heavy workload and also a great attitude. While technical skills can be acquired through software testing training, other skills such as analytical skills, communication skills and people skills need to be intrinsic to the individual and must be developed by the individual himself.

Academic Qualifications for Being a Testing Professional

Software testers are required to have a computer science academic background. Those with degrees such as BE, BTech, BCA, BSc Computers and MCA will be able to find employment easily. However, this does not mean that those who do not have a graduate degree in computer science cannot be software testers. Any individual with or without a graduate degree can be a software tester if he completes a software testing course from a reliable training institute. Along with the skills, one needs to have the passion for the profession and the desire to keep learning and updating knowledge and skills.

Career Prospects in Software Testing

Testing is one of the fastest expanding areas worldwide in terms of corporate IT expenditure. There are enormous growth opportunities in the field and software testers can expect good remunerations. A diverse range of sectors are leveraging IT to innovate and simplify business processes and therefore the need to develop software is immense. With this need, there is also a demand for professionals who can test this software. Realising the growing need for software testers, students are increasingly becoming interested in software testing courses.

Ikya Global is one of the few best software testing training institutes in Hyderabad that offer training at affordable prices along with placement assistance and certification.

Software Testing

Software testing can be termed as the system of performing a program or application with the purpose of ascertaining the software bugs. It can also be described as the method of authenticating and determining that a software program or application or product achieves the business and technical benchmarks that that brought about the design and development of the software works as expected.

Software testing can be broken down into the following:

1.) Process: Software testing is a process and not just a single activity.

2.) All Life Cycle Activities: Testing is a procedure that happens throughout the Software Development Life Cycle (SDLC). The procedure of blueprinting tests ahead of time in the life cycle can aid to thwart bugs from getting initiated in the code. This is also referred to as, “verifying the test basis via the test design”. The test basis consists of documents like requirements and design specifications.

3.) Static Testing: This can test and find out the defects without running the code. Static Testing is run during the process of verification, which includes analyzing of the documents, which includes the source code), and static analysis. This is a very useful and also cost effective manner of testing. Examples of static testing are reviewing, walkthrough, inspection, etc.

4.) Dynamic Testing:  In this, the software code is run to present the outcome of running tests. Dynamic testing is run at the time of the validation process. Examples of dynamic testing are unit testing, integration testing, system testing, etc.

5.)  Planning:  Proper planning has to be done as to what is to be accomplished. In this, the test activities are controlled, testing progress reported, and software status under testing environment.

6.)  Preparation:  Proper preparation has to be made as to what testing will be done by choosing the right test conditions and designing test cases.

7.)  Evaluation:  During the evaluation, the results need to be checked the software evaluated under the testing and the completion criteria, which assists in deciding as to whether the testing has been completed and if the software product has cleared all the tests.

8.)  Software and related work products:  Along with the code testing, requirement testing and design stipulations and related documents like operation, user, training material, etc., is important equally.

Why is software testing necessary?

Software testing is genuinely needed to bring out the defects and errors that were committed at the time of the development phase. This is needed as it makes sure of customer’s authenticity and satisfaction with the application that is developed. It is very critical to make assure the product’s quality.  Delivering the customers a quality product will definitely help in winning their assurance. Testing is an important requirement so as to be able to furnish the facilities to customers like handing over a software application of a high quality product which would need less maintenance cost and therefore result in a more correct, uniform, and dependable results. Testing is needed for an efficient functioning of the software application or product. It is important to make sure that the application does not lead into any breakdown as it can be very costly in the future and in the following stages of development.

When do defects in software testing arise?

Some of the reasons due to which software defects arise are:

1.) The personnel who use the software application may not have the much needed knowledge of the product.

2.) The possibility of the wrong way of using the software that would lead to the defect and the failure.

3.) Incorrect code put in by the software developers and also due to the errors present in the design.

4.) Wrong arrangement of the environment that is needed for the testing.

What are the principles of testing?

Principles of Testing:

1.) Testing brings out the defects if there are any: Testing can only depict the presence of defects, but it cannot prove if there are any defects or not. Even after thoroughly testing the software application and product, it would be hard to say that the is 100% defect free. In many ways, testing can only bring down the number of defects that are not discovered in the software.  Absence of errors is not the proof or the correctness of the software and the product.

2.) In-depth testing is not possible: Testing all the things that include all the combinations of the inputs and the preconditions is not at all possible. Therefore, rather than working on in-depth testing the risks and priorities can be used to center on the testing efforts.

3.) Early testing of the Product: In the software development growth, the process of testing must being as soon as possible and must be concentrated on fixed objectives.

4.) Defect clustering: It is during pre-release testing that there are a number of modules that contain most of the defects that are detected and also this is when most operational failures are shown.

5.) Pesticide paradox: Repeating the same test time and again will eventually lead to the same chain of the test cases and there will no longer be any new bugs to be found. In order to get back this “Pesticide Paradox”, it is extremely significant to assess the test cases at regular intervals; therefore, new and out of the ordinary tests would have to be written in order to discharge the different portions of the software or system to possibly discover more defects.

6.) Testing is dependent on the context: Testing is mainly based on the. Different tests are conducted on different sites. For instance, safety–critical software is tried out in a different way than that of an e-commerce site.

7) The fallacy of absence – of – errors: If the system that has bene developed has become unusable and is not able to meet he needs of the user and their expectation, then locating and correcting the defects would not help.
