Software testing jobs are the necessary part of software development. It requires specific methodologies to avoid unpredictable development times and error products. For any software development, planning is essential and testing is one of the key phase of it.
It is important to ensure the quality of product. Standard development methodologies include a set of basic testing mechanisms. It may include testing very small code step by step and finally the whole functionality of the application developed. There are 6 kinds of software testing methodologies which include:
Unit Tests
Unit Tests is the most basic testing procedure. It includes restricted yet well defined scope. The testing goes with the interaction of the code with memory only. It does not include any interaction with file systems, network and database. It allows the tester to check smallest units of code easily and proof-check if the units can work properly. Later, these small units are combined to further check them in a cohesive manner.
Integration Tests
This includes the interpretation of smaller units. It involves accessing databases, network and file systems. It helps revealing out the problems associated with network modules, small units of code and databases. For example; Unit 1 might not be giving data appropriately to the Unit 2 and such problems arise in the integration tests.
Functional Tests
This is the time to perform higher level of tests after the integration tests. Functional Tests check whether output is correct with respect to the input defined in the specification. The major focus of this test is to to know the final output. Knowing intermediate values is the concern.
Smoke Tests
After the Functional Tests, it’s time for Smoke Tests. Smoke Tests analogy is derived from the electronics where smoke comes out when circuits are not connected well. After a fresh installation, a simple test is done.
Regression Tests
Regression test is to rectify the bugs in a system that is affecting the core areas. It includes retesting all the modules.
Acceptance Tests
Acceptance Tests include the end level test. The tester checks every feature from the perspective of users. These tests take time to figure out the issue in the code if still there is any error. It is one of the crucial testing phase that helps creating better applications without any acceptance errors.
Conclusion
These methodologies help producing an error free and robust software to give desired output. These testing phases are the major aspects of testing jobs. Different software testers work on different stages of testing. One who has experience of testing of first and second stages can move ahead with better opportunities for the position of final testers.
