seven principles in software testing | testingshala | testing tutorials #sevenprinciples #softwaretesting #testingshala 1) Early testing When we start the testing at a very earlier stage the cost incurred will be very less hence it is always advisable to carry out testing in early phase itself. 2) Testing shows presence of defects It is important to find out new issues after each test completion to make the application as much as error free as possible. 3) Exhaustive testing is not possible Carrying out all possible combinations of tests are not very realistic hence must adopt the risk based testing where test prioritization is done. 4) Defect clustering Unstable area is spotted and test optimization is done effectively in such area. 5) Pesticide paradox If there are ten tests cases, while executing these tests every time new defects are seen this is called a pesticide paradox. 6) Testing is context dependent Though there are plenty of different tests the most beneficial and the test that is in alignment with the context of the application must be used. 7) Absence of errors fallacy Even though if it is 99% errors free it must still meet every requirements agreed upon with the clients.
