Introduction to the QUnit Module

The QUnit module provides a framework for automated testing.

It contains base classes for creating test cases and test suites. It also provides a dependency injection helper for mocking pre-existing classes without modifying their code.

It also provides a number of pre-defined testing functions for use in assertions.

Examples:

#!/usr/bin/env qore
# -*- mode: qore; indent-tabs-mode: nil -*-
 
%new-style
%enable-all-warnings
%require-types
%strict-args
 
%requires ../../qlib/QUnit.qm
 
#%include ./_some_module_to_test
 
%exec-class QUnitTest
 
public class QUnitTest inherits QUnit::Test {
    constructor() : Test("QUnitTest", "1.0") {
        addTestCase("What this method is testing", \testMethod(), NOTHING);
        addTestCase("Skipped test", \testSkipped(), NOTHING);
 
        # Return for compatibility with test harness that checks return value.
        set_return_value(main());
    }
 
    testMethod() {
        # Test against success
        testAssertion("success", \equals(), (True, True));
        # Test against something else
        testAssertion("failure", \equals(), (True, False), RESULT_FAILURE);
    }
 
    testSkipped() {
        # Skip this test
        testSkip("Because of the reason it skipped");
    }
}

#!/usr/bin/env qore
# -*- mode: qore; indent-tabs-mode: nil -*-
 
%new-style
%enable-all-warnings
%require-types
%strict-args
 
%requires ../../qlib/QUnit.qm
 
#%include ./_MODULE_TO_TEST_
 
%exec-class MyTestClass
 
public class MyTestClass inherits QUnit::DependencyInjectedTest {
    constructor() : DependencyInjectedTest("MyTestClass", "1.0") {
        addTestCase("Test something", \testMethod(), NOTHING);
 
        # Return for compatibility with test harness that checks return value.
        set_return_value(main());
    }
 
    # mandatory for tests with dependency injections
    private string getScriptPathImpl() {
        return get_script_path();
    }
 
    private performInjectionImpl() {
        # perform injections in builtin modules
        injectClass("MyClass", "Class");
        child.loadModule("reflection");
 
        # custom injections for the FixedLengthUtil module
        code inject = sub (Program p) {
            p.importClass("Aalt", "A", True);
            p.importClass("InputStreamLineIteratorFake", "Qore::InputStreamLineIterator", True);
        };
 
        injectUserModule("FixedLengthUtil", inject);
    }
 
    testMethod() {
        # Same test style as in TestExample.qtest
        assertTrue(True);
    }
}

Running tests

Tests are ran by simply executing the test script:

    qore test.qtest [OPTIONS]

A number of options is available, controlling the behaviour/output of the test

Supported output formats of test reports

Currently the module provides the following output formats:

plainquiet - human readable quiet format, prints only failures and a short summary at the end, which is also the default
plaintext - human readable format, prints one statement per test
junit - machine readable format for further processing

Release Notes

Version 0.4.3

added constructors for use with languages that don't support lvalue references (ex: Python) (issue 3934)

Version 0.4.2

allow QUnit to be used from other languages like Java (issue 3857)

Version 0.4.1

allow binary modules to be subjected to dependency injections (issue 3382)
allow tests to be nested (issue 3306)

Version 0.4

updated Test::testSkip() to use the reason argument a format string with vsprintf() (issue 3172)
fixed error reporting with type errors with number values (issue 2984)

Version 0.3.3

improved output in assertion failures for strings with special whitespace and for multi-line data structures (issue 2680)

Version 0.3.2

improved error location reporting by providing all stack location information up until the QUnit call to cover the case when multiple code layers are used such as one or more test modules (issue 1720)
overloaded testAssertionValue supports auto/number/float
more verbose output when number/float difference is found

Version 0.3.1

added the following methods:

Version 0.3

updated for complex types

Version 0.2

fixed showing the assertion location when there are test modules on top of QUnit.qm (issue 1046)

Version 0.1

initial version of module
