Members

assertEmpty alias assertEmpty = assertProp!("empty", true): Assert range isn't empty.
assertEqual alias assertEqual = assertEquality!true: Unittest functions which give out a message with the failing expression.
assertEquals alias assertEquals = assertEqual: Common mispelling.
assertNotEmpty alias assertNotEmpty = assertProp!("empty", false): Assert range isn't empty.
assertNotEqual alias assertNotEqual = assertEquality!false: Common mispelling.

_makeEnumAliases string _makeEnumAliases(): Export all enum members as aliases. This allows enums to be used as types and allows its members to be used as if they're defined in module scope.
assertErrorsWith void assertErrorsWith(lazy E expr, string msg, string file = __FILE__, size_t line = __LINE__): Verify that calling expr throws and contains the exception message msg.
enquote string enquote(T arg): Return string representation of argument. If argument is already a string or a character, enquote it to make it more readable.
getException Exc getException(lazy E expr, string file = __FILE__, size_t line = __LINE__): Return the exception of type Exc that is expected to be thrown when expr is evaluated.
getExceptionMsg string getExceptionMsg(lazy E expr, string file = __FILE__, size_t line = __LINE__): Return the exception message of an exception. If no exception was thrown, then a new exception is thrown to notify the user of the missing exception.
require T require(T value, Args args): Similar to enforce, except it can take a formatting string as the second argument. Note: Until Issue 8687 is fixed, file and line have to be compile-time arguments, which might create template bloat.
safeCast T safeCast(S s): See: https://github.com/slembcke/Chipmunk2D/issues/56

_ExportEnumMembers mixin template _ExportEnumMembers(E): Export all enum members as aliases. This allows enums to be used as types and allows its members to be used as if they're defined in module scope.

assertOp template assertOp(string op): Useful template to generate an assert check function
enforceEx template enforceEx(E): An overload of enforceEx which allows constructing the exception with the arguments its ctor supports. The ctor's last parameters must be a string (file) and size_t (line).
