DRAKE_ASSERT_NO_THROW

#define DRAKE_ASSERT_NO_THROW

(

statement

)

_DRAKE_TEST_NO_THROW(statement, GTEST_FAIL)

Same as DRAKE_EXPECT_NO_THROW, but halts the execution of the given test case on failure.

DRAKE_EXPECT_NO_THROW

#define DRAKE_EXPECT_NO_THROW

(

statement

)

_DRAKE_TEST_NO_THROW(statement, ADD_FAILURE)

Unittest helper to explicitly indicate that a statement should not throw an exception.

This should be used in place of EXPECT_NO_THROW because it will have useful information when a failure indeed happens.
