It works in both vanilla unittest, and also when run via nosetests, and also works in Python versions 2.7, 3.2, 3.3, and 3.4 (I did not specifically test 3.0.

To run all tests in a directory, right-click on the directory and select Run tests. The Android Plugin for Gradle compiles the local unit test code located in the default directory ( src/test/java/ ), builds a test app, and executes it locally using the default test runner class. Android Studio then displays the results in the Run window. Python unit test example. Now it’s time to write unit tests for our source class Person.In this class we have implemented two function – getname and setname. Now, we will test those function using unittest. In this area, you can configure a list of Name-Value pairs of environment variables that would be passed to the process started by the unit test runner and to all its child processes. These environment variables will override variables with the same names defined in your system, if any.

Python’s unittest module, sometimes referred to as PyUnit, isbased on the XUnit framework design by Kent Beck and Erich Gamma. Thesame pattern is repeated in many other languages, including C, perl,Java, and Smalltalk. The framework implemented by unittestsupports fixtures, test suites, and a test runner to enable automatedtesting for your code.

Basic Test Structure¶

Unit Test Runner C#

Tests, as defined by unittest, have two parts: code to managetest “fixtures”, and the test itself. Individual tests are created bysubclassing TestCase and overriding or adding appropriatemethods. For example,

In this case, the SimplisticTest has a single test()method, which would fail if True is ever False.

Running Tests¶

The easiest way to run unittest tests is to include:

at the bottom of each test file, then simply run the script directly from thecommand line:

This abbreviated output includes the amount of time the tests took, along witha status indicator for each test (the ”.” on the first line of output meansthat a test passed). For more detailed test results, include the -v option:

Test Outcomes¶

Tests have 3 possible outcomes:

ok

The test passes.

FAIL

The test does not pass, and raises an AssertionError exception.

ERROR

The test raises an exception other than AssertionError.

When a test fails or generates an error, the traceback is included in theoutput.

In the example above, testFail() fails and the traceback showsthe line with the failure code. It is up to the person reading thetest output to look at the code to figure out the semantic meaning ofthe failed test, though. To make it easier to understand the nature ofa test failure, the fail*() and assert*() methods allaccept an argument msg, which can be used to produce a more detailederror message.

Asserting Truth¶

Most tests assert the truth of some condition. There are a fewdifferent ways to write truth-checking tests, depending on theperspective of the test author and the desired outcome of the codebeing tested. If the code produces a value which can be evaluated astrue, the methods failUnless() and assertTrue() shouldbe used. If the code produces a false value, the methodsfailIf() and assertFalse() make more sense.

Testing Equality¶

As a special case, unittest includes methods for testing theequality of two values.

These special tests are handy, since the values being compared appearin the failure message when a test fails.

And when these tests are run:

Almost Equal?¶

In addition to strict equality, it is possible to test for nearequality of floating point numbers using failIfAlmostEqual()and failUnlessAlmostEqual(). Mcr200 software free download.

The arguments are the values to be compared, and the number of decimalplaces to use for the test.

Testing for Exceptions¶

As previously mentioned, if a test raises an exception other thanAssertionError it is treated as anerror. This is very useful for uncovering mistakes while you aremodifying code which has existing test coverage. There arecircumstances, however, in which you want the test to verify that somecode does produce an exception. For example, if an invalid value isgiven to an attribute of an object. In such cases,failUnlessRaises() makes the code more clear than trapping theexception yourself. Compare these two tests:

The results for both are the same, but the second test usingfailUnlessRaises() is more succinct.

Test Fixtures¶

Fixtures are resources needed by a test. For example, if you arewriting several tests for the same class, those tests all need aninstance of that class to use for testing. Other test fixtures includedatabase connections and temporary files (many people would argue thatusing external resources makes such tests not “unit” tests, but theyare still tests and still useful). TestCase includes aspecial hook to configure and clean up any fixtures needed by yourtests. To configure the fixtures, override setUp(). To cleanup, override tearDown().

When this sample test is run, you can see the order of execution of thefixture and test methods:

Test Suites¶

The standard library documentation describes how to organize testsuites manually. I generally do not use test suites directly, becauseI prefer to build the suites automatically (these are automated tests,after all). Automating the construction of test suites is especiallyuseful for large code bases, in which related tests are not all in thesame place. Tools such as nose make it easier to manage tests whenthey are spread over multiple files and directories.
