Qt Multiple tests Build Status

Purpose

The Qt Test library, as based on a lightweight philosophy, don't provide any facilities for run multiple tests cases in a single application. But that's can be a very useful feature for medium size applications.

Qt Multiple tests provide an easy solution : include an additionnal header and you are able to create several tests cases in your test suite. A single binary will allow to run one or all test cases. Reporting and re-run test is simplified. Parsing unit tests results will be simplified for external tools (IDE, continuous integration)

Qt Multiple tests is a rework on a original example provided by Rob Caldecott in his two of his posts : Running Multiple Unit Tests and Sample Multiple Unit Test Project .

Features

  • Simplicity of use : just include the header MultiTests.hh to your project
  • Choose to run all or a selection of the test case : option -case <casename>
  • List all tests functions from a case (or all cases) : option -functions
  • Summary of tests results in verbose output
  • Support some Qt Test runner options. For example you can have XML report
  • Qt4 / Qt5 compatibility
  • For Qt4 : Provide the exception thrown test (as exists in Qt5)

Requirements

  • A Qt application in QTest mode
    • For Qt4 : CONFIG += qtestlib
    • For Qt5 : QT += testlib widgets

How to use it

  1. Add the MultiTests.hh file to your project
  2. Create a test case. Register it using TEST_DECLARE
#ifndef TESTDUMMY_HH_
#define TESTDUMMY_HH_

#include "MultiTests.hh"

class Dummy_test : public QObject
{
    Q_OBJECT

private slots:
    // Test functions
    void obviousTest(void){
       QCOMPARE(1,1);
    }
};

TEST_DECLARE(Dummy_test);

#endif /* TESTDUMMY_HH_ */
  1. When you want to compile the unit tests, just run the MULTI_TESTS_MAIN instead of your main function :
#ifdef UNITTEST_MODE
    #include "MultiTests.hh"
    MULTI_TESTS_MAIN
    // Else run normal main function
#endif
  1. Compile the application and run it : the test case is executed
  2. Repeat the step 2 for add more tests cases

Example of execution :

********* Start testing of Dummy_test *********
Config: Using QTest library 4.8.6, Qt 4.8.6
PASS   : Dummy_test::initTestCase()
PASS   : Dummy_test::obviousTest()
PASS   : Dummy_test::cleanupTestCase()
********* Finished testing of Dummy_test *********
********* Start testing of StylesHandler_test *********
Config: Using QTest library 4.8.6, Qt 4.8.6
PASS   : StylesHandler_test::initTestCase()
FAIL!  : StylesHandler_test::totalFailure() Compared values are not the same

   Expected (QString("153")): 153
   Loc: [tests/StylesHandler_test.cpp(67)]
PASS   : StylesHandler_test::styleExist()
