Assertions

Oveview

Assertions work the same as expectations except they stop the execution of the test as soon as a failed condition is met.

ASSERT_TRUE

#define ASSERT_TRUE

(

expr

)

_PW_TEST_ASSERT(_PW_TEST_BOOL(expr, true))

See EXPECT_TRUE.

PW_TEST_ASSERT_OK

#define PW_TEST_ASSERT_OK

(

expr

)

Value:

  if (cpp20::is_constant_evaluated()) {                  \
    if (!::pw::unit_test::internal::Constexpr_EXPECT_OK( \
            ::pw::internal::ConvertToStatus(expr))) {    \
      return;                                            \
    }                                                    \

    ASSERT_EQ(::pw::internal::ConvertToStatus(expr), ::pw::OkStatus())

See PW_TEST_EXPECT_OK.

PW_TEST_ASSERT_OK_AND_ASSIGN

#define PW_TEST_ASSERT_OK_AND_ASSIGN	(		lhs,
			rexpr
	)

Value:

  _PW_TEST_ASSERT_OK_AND_ASSIGN_DETAIL(          \
      _PW_UNIQUE_IDENTIFIER_DETAIL(__LINE__), lhs, rexpr)

Executes an expression that returns a pw::Result or pw::StatusWithSize and assigns or moves that value to lhs if the error code is OK. If the status is non-OK, generates a test failure and returns from the current function, which must have a void return type.

Example: Declaring and initializing a new value. E.g.: PW_TEST_ASSERT_OK_AND_ASSIGN(auto value, MaybeGetValue(arg)); PW_TEST_ASSERT_OK_AND_ASSIGN(const ValueType value, MaybeGetValue(arg));

Example: Assigning to an existing value ValueType value; PW_TEST_ASSERT_OK_AND_ASSIGN(value, MaybeGetValue(arg));

The value assignment example would expand into something like: auto status_or_value = MaybeGetValue(arg); PW_TEST_ASSERT_OK(status_or_value.status()); value = status_or_value.ValueOrDie();

WARNING: PW_TEST_ASSERT_OK_AND_ASSIGN expand into multiple statements; it cannot be used in a single statement (e.g. as the body of an if statement without {})!

Parameters

[in]	lhs	Variable to assign unwrapped value to
[in]	rexpr	Expression to unwrap. Must be a Result or StatusWithSize.
