Eggs.Test

A minimal, header-only C++ test framework. Requires C++23.

Usage

#include <eggs/test.hpp>

TEST_CASE(my_test, "adds two integers") {
    CHECK(1 + 1 == 2);
    REQUIRE(1 + 1 == 2);  // stops the test case on failure
}

int main() {
    return eggs::test::run();
}

Assertion macros

CHECK(expr) — evaluates expr; reports failure and continues.
REQUIRE(expr) — like CHECK, but stops the current test case on failure.

CHECK_THROWS(expr) — passes if expr throws any exception.
CHECK_THROWS_AS(ExcType, expr) — passes if expr throws an exception of type ExcType; returns std::exception_ptr on success.
CHECK_CATCHES_AS(ExcType, expr) { } — like CHECK_THROWS_AS; the body runs on success with the caught exception bound to exc.
CHECK_NOTHROW(expr) — passes if expr does not throw.

Every CHECK_* macro has a REQUIRE_* variant that stops the test case on failure.
