Description

The test runner for the µTest++ framework.

The runner class is responsible for managing the registration and execution of test suites within the µTest++ framework. It maintains a collection of test suites, each of which registers itself automatically upon construction, enabling seamless integration and execution of tests across different components and folders of a project.

The test runner provides methods for initialising the test environment, registering test suites, retrieving the runner's name, and determining the overall test result via an exit code. It also offers an abort mechanism for terminating test execution in exceptional circumstances.

All members and methods are defined within the micro_os_plus::micro_test_plus namespace, ensuring clear separation from user code and minimising the risk of naming conflicts.

Public Constructors

runner()

micro_os_plus::micro_test_plus::runner::runner (const char * top_suite_name)

Deprecated constructor for the runner class.

Parameters

[in] top_suite_name

The name given to the implicit top suite. Defaults to an empty string.

Deprecated

Use the anonymous constructor.

The constructor initialises a new runner instance together with its top suite (top_suite_). If tracing is enabled, it outputs the function signature for diagnostic purposes.

abort()

void micro_os_plus::micro_test_plus::runner::abort (const reflection::source_location & sl=reflection::source_location::current())

Returns

exit_code()

int micro_os_plus::micro_test_plus::runner::exit_code (void)

Returns 0 if all tests were successful, 1 otherwise.

Parameters

None.

Returns

Integer exit code representing the overall test result.

Finalises the top suite by recording its end timestamp and notifying the reporter, then accumulates its totals into the runner totals. Subsequently invokes run_suites_() to sort, execute, and accumulate all registered child suites. Finally, records the session end timestamp, notifies the reporter, and returns 0 if all checks passed or 1 otherwise.

initialise()

suite & micro_os_plus::micro_test_plus::runner::initialise (int argc, char * argv=[], const char * top_suite_name="")

Initialises the test runner with command-line arguments.

Parameters

argc	The argument count from main().
argv	The argument vector from main().
top_suite_name	The name given to the implicit top suite. Defaults to an empty string.

Returns

Reference to the top-level test suite.

Captures command-line arguments, selects the reporter implementation (human or tap), starts session timing, and emits the initial reporter notifications for the session and top suite.

If the top suite name is not provided, it attempts to derive a name from argv[0] or defaults to "default suite".

If tracing is enabled, the command-line arguments are also logged for diagnostic purposes.

register_suite_()

void micro_os_plus::micro_test_plus::runner::register_suite_ (std::unique_ptr< class suite > suite)

protected

Registers a test suite with the runner.

Parameters

[in] suite

Owning pointer to the test suite to register.

Returns

Nothing.

Takes ownership of the supplied suite unique pointer and appends it to the internal children_suites_ vector, deferring execution until run_suites_() is called. If tracing is enabled, the suite name is logged for diagnostic purposes.

run_suites_()

void micro_os_plus::micro_test_plus::runner::run_suites_ (void)

protected virtual

Runs all registered test suites.

Parameters

None.

Sorts children_suites_ alphabetically by suite name using a selection sort on unique_ptr::swap, avoiding the -Waggregate-return diagnostic that std::sort would trigger on unique-pointer iterators. Each suite is assigned a 1-based index offset by the top-suite index, executed via suite::run(), and its totals are accumulated into the runner totals. The executed-subtest counter is not incremented; suites are not counted as subtests.

children_suites_

std::vector<std::unique_ptr<class suite> > micro_os_plus::micro_test_plus::runner::children_suites_

protected

Owning collection of dynamically registered child suites.

Each call to runner::suite() appends a new suite to this vector and runs it immediately. The vector retains ownership of all suites for the lifetime of the runner.
