Software testing-importance Guide


Scope of software testing:
Software testing is a process of analysis of a component by providing defined inputs and comparing the outputs to check the discrepancies between the desired and actual outputs and correct them.. The aim is to check whether the software meets the specific requirements, needs and expectations of the customer.


Why choose software testing career:

• There is a strong community
* Software testing is a safe career path
* It is worthwhile
* Academic background is not necessary
• You are constantly learning
* Importance and responsibility
• Flexibility
• There are many chances to experiment
* Decision on priority
* Analysis of data and delivery of results
* Building trust in the product
* Improvement of quality


Function Test Types:

• Unit test.
• Integration testing.
• System testing.
* Mental health testing.
* Smoke.
* Interface test.
• Regression.
* Beta / Acceptance Tests.



Application Of Test Methods

Black Box: in the black box Test, the AUT is validated against its requirements, taking into account the inputs and expected outputs, regardless of how the inputs are converted into outputs. Testers are least affected by the code that implements the application's business logic. There are primary techniques to design test cases for black box Tests:
• BVA (boundary value analysis)
* EP (equivalence class formation)
* Decision tables
* State transition tables (and diagrams)

White Box: the main focus of this methodology is on validating how the application's business logic is implemented through code. Internal structure of the application is tested, and the techniques available to do this are :
• Code coverage
* Path coverage


Grey Box: practically speaking, this is a mix of black box and white box. In Grey Box, the tester mainly tests the application as in black box. But for some vulnerable application modules, Tests are performed as a white box.

Application Test Cycles
As soon as the AUT is ready for testing, the practical Phase of the test cycle begins, in which the testers actually run the test cases on AUT. Note that here the test cycle, regardless of test levels (unit, module, Integration, System and user acceptance) and test environments (Dev, QA, Client Replica, Live) will be discussed.

Smoke test: the first testing cycle that is wide and shallow in approach. The smoking test is designed to ensure that there are no crashes in the application and that it is suitable for further Tests.

Sanity Testing: the 2’nd test cycle, which is deep in its approach. Its purpose is to verify that a particular module is functioning properly and is suitable for full testing.

Functional tests: the proper and complete examination of the application is carried out in this cycle. The focus of this work is to review the business logic of the application.

Regression tests: this is the last test cycle in which the Bugfixes and/or updates are checked. regression testing also ensures that there are no maltifunctions in other areas of AUT due to fixes and changes.



Non-functional test types :
• Performance testing
• Load testing
• Stress test
* Volume Testing
* Safety tests
* Compatibility testing
* Install Tests
* Recovery Tests
* Reliability testing
* Usability Tests
* Conformity assessment
* Localization Tests

Tools for automated software testing:

Tools that makes it easy to choose:
* Developer tools
* Functional Test Tools
* Load testing tools
* Performance monitoring and maintenance tools
