Despite the fact that many authors have made numerous attempts to arrange software testing process in chronological order, no universal solution has been introduced as far, the one, which would equally suitable for any project management methodology, any individual project and each of its stages.
If we try to describe chronology of software testing in one phrase then it would sound like that: test cases are becoming more and more complex therefore the testers more often have difficulties in selecting effective test cases for a particular type of testing.
Importance of test sequence. It is necessary to use simple positive test cases to test some service or an application; then one may gradually add negative test cases (but also just simple ones). Only after the most typical situations have been covered with simple test cases, you should move on to the more complex test cases (again, starting with the positive ones). This is not a dogmatic approach to test execution order, but you are recommended to consider it, because if the negative test cases are used during the initial stages (especially if they are complex ones) it may involve negative consequences: for example, the program may fail when performing simple tasks. Once again, when carrying out software testing the following sequence steps should occur:
- simple positive testing;
- simple negative testing;
- complex positive testing;
- complex negative testing.
Using outsourced software testing services you will be able to save on testing time and project development budget; at that, effective test cases will be written for your project so that to fully test each its feature or even aspect of its feature. Get your work done by someone else and nothing will prevent you from focusing on the core development.
Test sequence based on component hierarchy
- Bottom-up testing is an incremental approach to integration testing in which low level components are tested in the first instance and only then medium level and high level components are subjected to verification.
- Top-down testing is also an incremental approach to integration testing in which exactly the converse situation takes place – high level components undergo testing in the first place and then medium level and low level components are tested.
- Hybrid testing is a combination of bottom-up testing and top-down testing.
Do you feel like improving quality of your software and protecting yourself from market loss? if so, you need to thoroughly test your IT products, from development to deployment. Continuous integration services will help you to detect defects in the fastest way and locate these problems quite easily.
