Who is tester

Unit testing is generally done by the programming team themselves. It could be manual but most often using an automated testing framework such as Junit. Generally speaking the testing team does not care about unit testing there sole job is to test whether the system works to spec. They do not need to know how it was built, what languages frameworks were used etc. Its almost impossible to write code without introducing bugs.

Worse its almost impossible to specify a module correctly. So unless your name is "Bill Joy" you are going to introduce bugs when you code. Even if you code precisely to spec the finished module can still be wrong.

All good programmers that I know believe there programs to be full of un-spotted bugs, and know in there hearts that know matter how careful they are they will have done something wrong.

Edge cases can be a nightmare to code correctly should a loop execute n times or n - 1 times. Interface specs can be in-complete and ambiguous; you read the docs but you really don't know whats going to happen when you call the API.

The failures could be trivial, they could be deeply embarrassing, or, they could be disastrous. Sign up to join this community. The best answers are voted up and rise to the top.

KilianFoth that's not what I was looking for. They're testing to make sure you didn't overlook something. When you wrote the tests, you tested what you thought could go wrong - but in reality there's a whole lot more that can go awry.

A good tester knows this and will actively look for such cases. It's a different mindset, really - one tries to create things, the other tries to break them. Show 4 more comments.

Usually, the system as a whole is tested as a black box, but sometimes the test scripts are more on an integration or unit-test level with a white-box system.

Test engineers write 'test scripts' that are meant to be executed by hand, either by themselves or by the manual testers. Manual testers are the ones that mainly execute manual test scripts and play around with the system as a kind of power user.

The testing process involves evaluating the features of the software product for requirements in terms of any missing requirements, bugs or errors, security, reliability and performance. This is not the complete list as there are more than types of testing types and still adding.

Unit Testing: This software testing basic approach is followed by the programmer to test the unit of the program.

It helps developers to know whether the individual unit of the code is working properly or not. Integration testing: It focuses on the construction and design of the software.

You need to see that the integrated units are working without errors or not. System testing: In this method, your software is compiled as a whole and then tested as a whole. This testing strategy checks the functionality, security, portability, amongst others. Program Testing in software testing is a method of executing an actual software program with the aim of testing program behavior and finding errors.

The software program is executed with test case data to analyse the program behavior or response to the test data. A good program testing is one which has high chances of finding bugs.
