vsut 1.5.3

A simple unit testing framework for Python 3.

VSUT is a simple unit test framework for Python.

Usage

A unit can be described , like follows:

...
class UnitTest(vsut.unit.Unit):

    def testComponentOne(self):
        ...
    def testComponentTwo(self):
        ...

Any methods that start with ‘test’ will be executed automatically, once the case is run.

Asserts & Fail Conditions

The following methods can be used in a test-case to check for success or failure:

• assertEqual(expected, actual) - Checks for equality of the two arguments.

• assertNotEqual(expected, actual) - Checks for inequality of the two arguments.

• assertTrue(expected) - Checks whether the argument is the boolean value True.

• assertFalse(expected) - Checks whether the argument is the boolean value False.

• assertIn(expected, collection) - Checks whether the argument is in the collection.

• assertNotIn(expected, collection) - Checks whether the argument is not in the collection.

• assertIs(expected, actual) - Checks whether the value is the expected.

• assertIsNot(expected, actual) - Checks whether the value is not the expected.

• assertIsNone(expected) - Checks whether the argument is None.

• assertIsNotNone(expected) - Checks whether the argument is not None.

• assertRaises(exception, func, *args) - Checks whether the function ‘func’ raises an exception of the type ‘exception’.

For any of these methods a message parameter can be specified, that will be printed instead of the default message.

Example

...
assertEqual(True, False, message="True is not False")
...

Full Example

from vsut.unit import Unit
from vsut.assertion import assertEqual

class TestCase(Unit):

    def testExample(self):
        a = True
        b = True
        c = False
        assertEqual(a, b)
        assertEqual(b, c)

Running units

Units can be run with the test runner, as follows:

python runner.py [--format=table] module.TestClass module1.TestClass1 ...

The --format argument is optional and specifies the method of formatting the output. Available methods are table and csv, with table being the default.

The separator for the csv-data can be specified with the parameter --separator.

NOTE: Some characters require escaping with \, as they are special characters.

Output as Table

Output as a table can look like this for example:

```

[TestCase]

Id | Name | Status | Time | Assert | Message

0 | testAssertEqual | OK | 0.000003 | |

1 | testAssertEqualFail | OK | 0.000008 | |

2 | testAssertFalse | OK | 0.000001 | |

3 | testAssertIn | OK | 0.000002 | |

4 | testAssertIs | OK | 0.000001 | |

5 | testAssertIsNone | OK | 0.000002 | |

6 | testAssertIsNot | OK | 0.000001 | |

7 | testAssertIsNotNone | OK | 0.000001 | |

8 | testAssertNotEqual | OK | 0.000001 | |

9 | testAssertNotIn | OK | 0.000002 | |

10 | testAssertRaises | OK | 0.000005 | |

11 | testAssertTrue | OK | 0.000002 | |

12 | testFailWithCustomMessage | FAIL | 0.000003 | assertEqual | A custom message.

13 | testWillFail | FAIL | 0.000003 | assertEqual | 1 != 2

14 | testWillFailToo | FAIL | 0.000003 | assertNotEqual | 1 == 1

#### Output as CSV
Output as CSV can look like this for example:

TestCase

0,testAssertEqual,OK,0.000004

1,testAssertEqualFail,OK,0.000011

2,testAssertFalse,OK,0.000002

3,testAssertIn,OK,0.000004

4,testAssertIs,OK,0.000004

5,testAssertIsNone,OK,0.000002

6,testAssertIsNot,OK,0.000004

7,testAssertIsNotNone,OK,0.000002

8,testAssertNotEqual,OK,0.000003

9,testAssertNotIn,OK,0.000002

10,testAssertRaises,OK,0.000007

11,testAssertTrue,OK,0.000003

12,testFailWithCustomMessage,FAIL,0.000006,assertEqual,A custom message.

13,testWillFail,FAIL,0.000007,assertEqual,1 != 2

14,testWillFailToo,FAIL,0.000006,assertNotEqual,1 == 1
