BOOST_TEST(expression)

If expression is false increases the error count and outputs a message containing expression.

BOOST_TEST_NOT(expression)

If expression is true increases the error count and outputs a message containing !(expression).

BOOST_ERROR(message)

Increases error count and outputs a message containing message.

BOOST_TEST_EQ(expr1, expr2)

If expr1 == expr2 is not true increases the error count and outputs a message containing both expressions.

BOOST_TEST_NE(expr1, expr2)

If expr1 != expr2 is not true increases the error count and outputs a message containing both expressions.

BOOST_TEST_LT(expr1, expr2)

If expr1 < expr2 is not true increases the error count and outputs a message containing both expressions.

BOOST_TEST_LE(expr1, expr2)

If expr1 <= expr2 is not true increases the error count and outputs a message containing both expressions.

BOOST_TEST_GT(expr1, expr2)

If expr1 > expr2 is not true increases the error count and outputs a message containing both expressions.

BOOST_TEST_GE(expr1, expr2)

If expr1 >= expr2 is not true increases the error count and outputs a message containing both expressions.

BOOST_TEST_CSTR_EQ(expr1, expr2)

Specialization of BOOST_TEST_EQ which interprets expr1 and expr2 as pointers to null-terminated byte strings (C strings). If std::strcmp(expr1, expr2) != 0, increase the error count and output a message containing both expressions.

BOOST_TEST_CSTR_NE(expr1, expr2)

Specialization of BOOST_TEST_NE which interprets expr1 and expr2 as pointers to null-terminated byte strings (C strings). If std::strcmp(expr1, expr2) == 0, increase the error count and output a message containing both expressions.

BOOST_TEST_ALL_EQ(begin1, end1, begin2, end2)

Compares the content of two sequences. If they have different sizes, or if any pairwise element differs, increases the error count and outputs a message containing at most 8 differing elements.

BOOST_TEST_ALL_WITH(begin1, end1, begin2, end2, predicate)

Compares the content of two sequences. If they have different sizes, or if any pairwise element do not fulfill the binary predicate, increases the error count and outputs a message containing at most 8 differing elements.

BOOST_TEST_THROWS(expr, excep)

If BOOST_NO_EXCEPTIONS is not defined and if expr does not throw an exception of type excep, increases the error count and outputs a message containing the expression.

If BOOST_NO_EXCEPTIONS is defined, this macro expands to nothing and expr is not evaluated.

int boost::report_errors()

Return the error count from main.

#include <boost/core/lightweight_test.hpp>

int sqr( int x )
{
    return x * x;
}

int main()
{
    BOOST_TEST( sqr(2) == 4 );
    BOOST_TEST_EQ( sqr(-3), 9 );

    return boost::report_errors();
}

#define BOOST_TEST_TRAIT_TRUE((Trait)) /*unspecified*/
#define BOOST_TEST_TRAIT_FALSE((Trait)) /*unspecified*/
#define BOOST_TEST_TRAIT_SAME(Type1, Type2) /*unspecified*/

BOOST_TEST_TRAIT_TRUE((Trait))

If Trait::value != true increases the error count and outputs a message containing Trait. Note the double set of parentheses; these enable Trait to contain a comma, which is common for templates.

BOOST_TEST_TRAIT_FALSE((Trait))

If Trait::value != false increases the error count and outputs a message containing Trait. Note the double set of parentheses.

BOOST_TEST_TRAIT_SAME(Type1, Type2)

If the two types are not the same, increases the error count and outputs a message containing them. This macro requires that the compiler supports variadic macros and __VA_ARGS__. (Note that unlike BOOST_TEST_TRAIT_TRUE and BOOST_TEST_TRAIT_FALSE, this macro only requires a single set of parentheses.)

#include <boost/core/lightweight_test_trait.hpp>
#include <boost/core/is_same.hpp>

template<class T, class U> struct X
{
    typedef T type;
};

using boost::core::is_same;

int main()
{
    BOOST_TEST_TRAIT_TRUE(( is_same<X<int, long>::type, int> ));

    BOOST_TEST_TRAIT_SAME( X<int, long>::type, int );

    return boost::report_errors();
}
