Detailed Description

reporter_tap provides a concrete implementation of the reporter abstract interface that formats test results according to the Test Anything Protocol (TAP). It accumulates output in an internal string buffer and writes it to the standard output stream.

Users who require custom output behaviour (e.g. redirecting to a serial port on bare-metal targets) may derive a new class from reporter and supply an instance via the reporter global pointer before calling initialize().

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.

Constructor & Destructor Documentation

◆ reporter_tap() [1/3]

micro_os_plus::micro_test_plus::reporter_tap::reporter_tap ( std::unique_ptr< std::vector< std::string_view > > argvs )

Parameters

argvs Owning pointer to the command-line arguments vector; the reporter takes ownership via move.

Delegates construction to the reporter base class with the supplied argument vector. If tracing is enabled, the function signature is output for diagnostic purposes.

Definition at line 83 of file reporter-tap.cpp.

Member Function Documentation

◆ begin_session()

void micro_os_plus::micro_test_plus::reporter_tap::begin_session ( runner & runner )

overridevirtual

Parameters

runner Reference to the test runner.

Returns: Nothing.

If verbosity is not silent, emits a blank line to stdout and then calls write_info_() to output build and environment information. The TAP version header "TAP version 14" is then written to both the output file (if open) and stdout. The add_empty_line_ flag is cleared so that the first suite header is not separated by an extra blank line.

◆ begin_subtest()

void micro_os_plus::micro_test_plus::reporter_tap::begin_subtest ( subtest & subtest )

overridevirtual

Parameters

subtest Reference to the subtest.

Returns: Nothing.

Validates that the output buffer is empty at subtest start; if not, the buffer is written to stdout, the stream is flushed, and execution is aborted. A "# Subtest: <name>" comment line (indented according to nesting depth) is written to the output file and, under normal or verbose verbosity, to stdout as well.

Parameters

suite Reference to the test suite.

Returns: Nothing.

Emits a "# Subtest: <name>" comment line to mark the start of a TAP subtest block for the suite. The line is written to the output file when one is open. Under normal or verbose verbosity, it is also written to stdout, preceded by a blank line when add_empty_line_ is set.

Parameters

runner Reference to the test runner.

Returns: Nothing.

Emits the TAP plan line (1..N, where N is the total number of test suites) followed by a comment line summarising successful checks, failed checks, executed test cases, elapsed time, and suite count. Both lines are written to the output file when one is open. When verbosity is set to quiet, the plan is replaced by 1..0 to produce a valid skipped-test TAP document.

reporter & micro_os_plus::micro_test_plus::reporter::operator<< ( reporter &(* func )(reporter &) )

Parameters

func	Function pointer to the stream manipulator.

Returns: Reference to the current reporter instance.

This operator overload enables manipulators, such as endl, to be used with the reporter stream in a manner similar to standard C++ streams. When a manipulator function is passed, it is invoked with the current reporter instance, allowing for seamless integration of stream operations and improved readability of test output across all test cases and folders.

◆ operator<<() [8/9]

template<typename T>

reporter & micro_os_plus::micro_test_plus::reporter::operator<< ( T * v )

Template Parameters

T	The type of the pointer.

Parameters

v	The pointer value to output.

Returns: Reference to the current reporter instance.

This operator overload enables the reporter to output pointer values in a consistent and readable format.

Null pointers are always rendered as the string "nullptr", regardless of the platform, avoiding platform-specific behaviour such as "(nil)" on Linux/glibc or "0x0" on macOS.

Non-null pointers are formatted as a hexadecimal address using snprintf with the p format specifier. The resulting string is appended to the internal output buffer, allowing pointer values to be included in test reports and diagnostics.

This approach provides clear and unambiguous representation of pointer addresses, which is particularly useful for debugging and verifying pointer-related test cases.

◆ operator<<() [9/9]

template<class T>
requires std::is_arithmetic_v<T>

reporter & micro_os_plus::micro_test_plus::reporter::operator<< ( T v )

Template Parameters

T	The arithmetic type.

Parameters

v	The value to output.

Returns: Reference to the current reporter instance.

This template operator overload allows the reporter to output values of any arithmetic type (integral or floating-point) in a consistent and readable format. The value is formatted using the append_number_ helper function, which handles the conversion to a string representation with appropriate type suffixes where applicable (e.g., "f" for float, "l" for long double). This enables numeric values to be included in test reports and diagnostics in a clear and unambiguous manner, supporting the verification of test cases that involve arithmetic expressions and comparisons.

Member Data Documentation

◆ add_empty_line_

bool micro_os_plus::micro_test_plus::reporter::add_empty_line_ { true }

protectedinherited

Used to nicely format the output.

Definition at line 572 of file reporter.h.

572{ true };

◆ argvs_

std::unique_ptr<std::vector<std::string_view> > micro_os_plus::micro_test_plus::reporter::argvs_ {}

protectedinherited

596{};

Referenced by reporter(), and write_info_().

◆ buffer_

std::string micro_os_plus::micro_test_plus::reporter::buffer_ {}

protectedinherited

Accumulates all reporter output until it is written to standard output or the output file via write_buffer_to_stdout() or write_buffer_to_file_().

Definition at line 552 of file reporter.h.

552{};

◆ colours_

detail::colours micro_os_plus::micro_test_plus::reporter::colours_ {}

protectedinherited

Definition at line 542 of file reporter.h.

◆ expression_

detail::expression_formatter micro_os_plus::micro_test_plus::reporter::expression_ { colours_ }

protectedinherited

Used in pass() and fail() to format expression values before appending the result to buffer_. Will also be used by detail::deferred_reporter to pre-format expressions at construction time.

Definition at line 563 of file reporter.h.

563{ colours_ };

Referenced by expression().

◆ output_file_

FILE* micro_os_plus::micro_test_plus::reporter::output_file_ { nullptr }

protectedinherited

When non-null, all output is written to this file instead of standard output. The reporter does not own the file; the caller is responsible for its lifetime.

Definition at line 591 of file reporter.h.

591{ nullptr };

◆ output_file_path_

const char* micro_os_plus::micro_test_plus::reporter::output_file_path_ { nullptr }

protectedinherited

When non-null, write_buffer_to_file_() writes accumulated output to this path in addition to (or instead of) standard output.

Definition at line 581 of file reporter.h.

581{ nullptr };
