Detailed Description

Runs a set of unit tests.

You can instantiate one of these objects and use it to invoke tests on a set of UnitTest objects.

By using a subclass of UnitTestRunner, you can intercept logging messages and perform custom behaviour when each test completes.

addFail()

void juce::UnitTestRunner::addFail ( const String &  failureMessage )

addPass()

void juce::UnitTestRunner::addPass ( )

beginNewTest()

void juce::UnitTestRunner::beginNewTest ( UnitTest *  test, const String &  subCategory  )

endTest()

getNumResults()

int juce::UnitTestRunner::getNumResults ( ) const

noexcept

Returns the number of TestResult objects that have been performed.

getResult

getResult()

const TestResult* juce::UnitTestRunner::getResult ( int  index ) const

noexcept

Returns one of the TestResult objects that describes a test that has been run.

getNumResults

logMessage()

virtual void juce::UnitTestRunner::logMessage ( const String &  message )

protectedvirtual

Logs a message about the current test progress.

By default this just writes the message to the Logger class, but you could override this to do something else with the data.

resultsUpdated()

virtual void juce::UnitTestRunner::resultsUpdated ( )

protectedvirtual

Called when the list of results changes.

You can override this to perform some sort of behaviour when results are added.

runAllTests()

void juce::UnitTestRunner::runAllTests

(

int64

randomSeed = 0

)

Runs all the UnitTest objects that currently exist.

This calls runTests() for all the objects listed in UnitTest::getAllTests().

If you want to run the tests with a predetermined seed, you can pass that into the randomSeed argument, or pass 0 to have a randomly-generated seed chosen.

runTests()

void juce::UnitTestRunner::runTests	(	const Array< UnitTest * > &	tests,
		int64	randomSeed = 0
	)

Runs a set of tests.

The tests are performed in order, and the results are logged. To run all the registered UnitTest objects that exist, use runAllTests().

If you want to run the tests with a predetermined seed, you can pass that into the randomSeed argument, or pass 0 to have a randomly-generated seed chosen.

runTestsInCategory()

void juce::UnitTestRunner::runTestsInCategory	(	const String &	category,
		int64	randomSeed = 0
	)

Runs all the UnitTest objects within a specified category.

This calls runTests() for all the objects listed in UnitTest::getTestsInCategory().

If you want to run the tests with a predetermined seed, you can pass that into the randomSeed argument, or pass 0 to have a randomly-generated seed chosen.

setAssertOnFailure()

void juce::UnitTestRunner::setAssertOnFailure ( bool  shouldAssert )

noexcept

Sets a flag to indicate whether an assertion should be triggered if a test fails.

This is true by default.

setPassesAreLogged()

void juce::UnitTestRunner::setPassesAreLogged ( bool  shouldDisplayPasses )

noexcept

Sets a flag to indicate whether successful tests should be logged.

By default, this is set to false, so that only failures will be displayed in the log.

shouldAbortTests()

virtual bool juce::UnitTestRunner::shouldAbortTests ( )

protectedvirtual

This can be overridden to let the runner know that it should abort the tests as soon as possible, e.g.

because the thread needs to stop.
