Value assertions

  • _AFT.assertEvalToTrue(value)

    Assert that a given value evals to true. Lua coercion rules are applied so that values like 0,”“,1.17 succeed in this assertion. If provided, extra_msg is a string which will be printed along with the failure message.

  • _AFT.assertEvalToFalse(Value)

    Assert that a given value eval to false. Lua coercion rules are applied so that nil and false succeed in this assertion. If provided, extra_msg is a string which will be printed along with the failure message.

  • _AFT.assertIsTrue(value)

    Assert that a given value compares to true. Lua coercion rules are applied so that values like 0, “”, 1.17 all compare to true.

  • _AFT.assertIsFalse(value)

    Assert that a given value compares to false. Lua coercion rules are applied so that only nil and false all compare to false.

  • _AFT.assertIsNil(value)

    Assert that a given value is nil .

  • _AFT.assertNotIsNil(value)

    Assert that a given value is not nil . Lua coercion rules are applied so that values like 0, "", false all validate the assertion. If provided, extra_msg is a string which will be printed along with the failure message.

  • _AFT.assertIs(actual, expected)

    Assert that two variables are identical. For string, numbers, boolean and for nil, this gives the same result as assertEquals() . For the other types, identity means that the two variables refer to the same object.

    Example :

    lua `s1='toto' s2='to'..'to' t1={1,2} t2={1,2} luaunit.assertIs(s1,s1) -- ok luaunit.assertIs(s1,s2) -- ok luaunit.assertIs(t1,t1) -- ok luaunit.assertIs(t1,t2) -- fail`

  • _AFT.assertNotIs(actual, expected)

    Assert that two variables are not identical, in the sense that they do not refer to the same value. See assertIs() for more details.
