It is the first level software testing method, where a small part of the code has tests, this is used for the software quality and productivity. We have used white box testing for using the Unit testing.
- Test fixture : it is to create the baseline for running the test in a fixed environment in which tests are run or it is repeatable.
- Test case : A test case is the set of condition which is used determined the check the condition under the system.
- Test suits : test suit is the growing number of test cases,it needs for categories to increase as well. Test suit is similar as shelves, the group test case together.
- Test runner : this test is done by the user in the defined time and along with their outcome.
Basic test structure
import unittest class BasicTest(unittest.TestCase): def check(self): self.assertTrue(True) if __name__ == '__main__': unittest.main()
This is the basic code of using the unittest framework, which is having a single test. This test () unittest method fails if FALSE is returned instead of TRUE.

OK : its mean all the test is passed
FAIL : It is mean test is not passed and Assertion Error Raised
ERROR : this mean test cases raised the error
import unittest class Test_Method_String(unittest.TestCase): def set(self): pass def teststring_A(self): self.assertEqual( 'A'*4, 'AAAA') def TEST_UPPER(self): self.assertEqual('example'.upper(), 'example') def TEST_IS_UPPER(self): self.assertTrue('EXAMPLE'.isupper()) self.assertFalse('Example'.isupper()) def TEST_STRIP(self): string = 'salesforcedrillers' self.assertEqual(s.strip('sales'), 'forcedrillers') def TEST_SPLIT(self): s = 'SALES FORCE' self.assertEqual(s.split(), ['SALES', 'FORCE']) with self.assertRaises(TypeError): s.split(2) if __name__ == '__main__': unittest.main()

In this program we have covered 5 different type string methods.
Basic Term which is Used in Program
assertEqual(): checking that the result is the same as expected.
assertTrue() / assertFalse() – this method is used to check that result is true or false
assertRaises() this method is used for raise the specific exception
