Level test unit testing, the minimum unit in which individual portions / components (referred to as cells) is tested to determine whether they are suitable for use.

Write and execute unit test cases by the developer (generally, of course, there are two general case) is completed to ensure that each unit will work as expected. Minimum portion of the various components, such as test subjects a function, class, interface or the like.

If a function, for example, then the input parameters passed to the function, check whether the function should return expectations. The main purpose of this test is to check whether the unit is working as designed, and more rational handling errors and exceptions, and be compatible with a variety of forward, reverse the situation.

Unit test is considered a white box. This is the lowest level of the test layer, prior to the start of integration testing.

Guide unit test cases:

Unit test plans / cases should be provided separately and should not be combined with other steps. Try all possible test programs, including unusual and alternative processes. Once the project enters the construction phase, developers will tend to only test cases have been completed successfully or in the case of coding.
Software development and unit tests need to be divided into different stages, and accordingly arrange delivery time.
The unit needs the test results as a separate deliverable processing. This will help filter out some errors in business processes at an early stage, rather than integration testing or system testing.
By statistical planning, execution, and failed test case by counting the master project schedule.
Try to make some immediate testing in the development process.
