Software Testing - Quick Guide. Software Testing - Quick Guide. Software Testing - Overview. What is Testing? Testing is the process of evaluating a system or its component(s) with the intent to find whether it satisfies the specified requirements or not. In simple words, testing is executing a system in order to identify any gaps, errors, or missing requirements in contrary to the actual requirements.

According to ANSI/IEEE 1. Testing can be defined as - A process of analyzing a software item to detect the differences between existing and required conditions (that is defects/errors/bugs) and to evaluate the features of the software item. Who does Testing? It depends on the process and the associated stakeholders of the project(s). In the IT industry, large companies have a team with responsibilities to evaluate the developed software in context of the given requirements. Moreover, developers also conduct testing which is called Unit Testing. In most cases, the following professionals are involved in testing a system within their respective capacities: Software Tester.

Software Developer. Project Lead/Manager. End User. Different companies have different designations for people who test the software on the basis of their experience and knowledge such as Software Tester, Software Quality Assurance Engineer, QA Analyst, etc.

It is not possible to test the software at any time during its cycle. The next two sections state when testing should be started and when to end it during the SDLC. When to Start Testing? An early start to testing reduces the cost and time to rework and produce error- free software that is delivered to the client.

However in Software Development Life Cycle (SDLC), testing can be started from the Requirements Gathering phase and continued till the deployment of the software. It also depends on the development model that is being used.

For example, in the Waterfall model, formal testing is conducted in the testing phase; but in the incremental model, testing is performed at the end of every increment/iteration and the whole application is tested at the end. Testing is done in different forms at every phase of SDLC: During the requirement gathering phase, the analysis and verification of requirements are also considered as testing. Reviewing the design in the design phase with the intent to improve the design is also considered as testing. Testing performed by a developer on completion of the code is also categorized as testing.

When to Stop Testing? It is difficult to determine when to stop testing, as testing is a never- ending process and no one can claim that a software is 1. The following aspects are to be considered for stopping the testing process: Testing Deadlines. Completion of test case execution. Completion of functional and code coverage to a certain point. Bug rate falls below a certain level and no high- priority bugs are identified. Management decision.

Verification & Validation. These two terms are very confusing for most people, who use them interchangeably. The following table highlights the differences between verification and validation. S. N. Verification. Validation. 1Verification addresses the concern: . Early testing saves both time and cost in many aspects, however reducing the cost without testing may result in improper design of a software application rendering the product useless. Myth 2 : Testing is Time- Consuming.

Reality : During the SDLC phases, testing is never a time- consuming process. However diagnosing and fixing the errors identified during proper testing is a time- consuming but productive activity. Myth 3 : Only Fully Developed Products are Tested. Reality : No doubt, testing depends on the source code but reviewing requirements and developing test cases is independent from the developed code.

However iterative or incremental approach as a development life cycle model may reduce the dependency of testing on the fully developed software. Myth 4 : Complete Testing is Possible. Reality : It becomes an issue when a client or tester thinks that complete testing is possible.

It is possible that all paths have been tested by the team but occurrence of complete testing is never possible. There might be some scenarios that are never executed by the test team or the client during the software development life cycle and may be executed once the project has been deployed. Myth 5 : A Tested Software is Bug- Free. Reality : This is a very common myth that the clients, project managers, and the management team believes in. No one can claim with absolute certainty that a software application is 1. Myth 6 : Missed Defects are due to Testers. Reality : It is not a correct approach to blame testers for bugs that remain in the application even after testing has been performed.

This myth relates to Time, Cost, and Requirements changing Constraints. However the test strategy may also result in bugs being missed by the testing team. Myth 7 : Testers are Responsible for Quality of Product. Reality : It is a very common misinterpretation that only testers or the testing team should be responsible for product quality. Testers’ responsibilities include the identification of bugs to the stakeholders and then it is their decision whether they will fix the bug or release the software. Releasing the software at the time puts more pressure on the testers, as they will be blamed for any error. Myth 8 : Test Automation should be used wherever possible to Reduce Time.

Reality : Yes, it is true that Test Automation reduces the testing time, but it is not possible to start test automation at any time during software development. Test automaton should be started when the software has been manually tested and is stable to some extent. Moreover, test automation can never be used if requirements keep changing.

Myth 9 : Anyone can Test a Software Application. Reality : People outside the IT industry think and even believe that anyone can test a software and testing is not a creative job. However testers know very well that this is a myth.

Thinking alternative scenarios, try to crash a software with the intent to explore potential bugs is not possible for the person who developed it. Myth 1. 0 : A Tester's only Task is to Find Bugs. Reality : Finding bugs in a software is the task of the testers, but at the same time, they are domain experts of the particular software. Developers are only responsible for the specific component or area that is assigned to them but testers understand the overall workings of the software, what the dependencies are, and the impacts of one module on another module.

Software Testing - QA, QC & Testing. Testing, Quality Assurance, and Quality Control. Most people get confused when it comes to pin down the differences among Quality Assurance, Quality Control, and Testing. Although they are interrelated and to some extent, they can be considered as same activities, but there exist distinguishing points that set them apart. The following table lists the points that differentiate QA, QC, and Testing. Quality Assurance.

Quality Control. Testing. QA includes activities that ensure the implementation of processes, procedures and standards in context to verification of developed software and intended requirements. It includes activities that ensure the verification of a developed software with respect to documented (or not in some cases) requirements. It includes activities that ensure the identification of bugs/error/defects in a software.

Focuses on processes and procedures rather than conducting actual testing on the system. Focuses on actual testing by executing the software with an aim to identify bug/defect through implementation of procedures and process.

Focuses on actual testing. Process- oriented activities. Product- oriented activities. Product- oriented activities.

Preventive activities. It is a corrective process. It is a preventive process. It is a subset of Software Test Life Cycle (STLC). QC can be considered as the subset of Quality Assurance.

When I started my career as a software tester, we were following V – model which is an enhancement of the waterfall model. It was introduced due to several reasons. In this article, we are going to analyse if early end- to- end testing is a better approach or not. Early end- to- end testing has some dependencies and advantages.
