We all make mistakes. Some of those mistakes are unimportant, but some of them are expensive or dangerous. To ensure that what we create does what it’s supposed to do software testing is important. Software testing is essential since it makes sure of the customer’s reliability and their satisfaction in the application. For quality product delivery, for an effective performance of software or software application, to ensure the results software testing is necessary.
“I get paid to tell people that they have made mistakes!!”
WHAT IS SOFTWARE TESTING?
An activity to check whether the actual results match the expected results and to ensure that the software system is defect free is software testing. It involves execution of a software component or system component to evaluate one or more properties of interest. It’s the process of validating and verifying a software program or application or product. Testing is a process rather than a single activity. Every software product release is done only after testing since software testing is the backbone for the software industry. No amount of testing can prove software right; a single test can prove software wrong.
It takes automation tool support to execute the test cases. Automated testing is good for large project. Automation Testing uses automation tools to run tests that repeat predefined actions and matches the developed program’s real results. If the project prospects and results align, and is behaving as it should, and you are likely bug free. If not aligned, there is a problem that requires to be addressed. You have to look at your code, change it, and continue testing until the actual and expected outcomes align.
To run tests manually, software developers uses Manual testing method. They are carried out manually as well as automatically. Their types are
Black Box Testing: Tests the functionalities and requirements of the system. It does not test the internal part of the system.
White Box Testing (Glass box Testing): It is based on information of the internal logic of an application’s code. Works on Internal working code of the system.
Integration Testing: Testing method to verify joint functionality after integration. Type of testing applicable to client/server and the distributed systems.
Unit Testing: Test specific component of software or module which is done by programmers and not by testers.
