Compare expectedResult with formatting value via format.

Synopsis

Declared in <bslfmt_formattertestutil.h>

template<class t_TYPE>
static
bool
testEvaluateFormat(
    bsl::string* message,
    bsl::basic_string_view<wchar_t> expectedResult,
    bool alsoTestOracle,
    std::wformat_string<t_TYPE> fmt,
    t_TYPE&& value);

Description

Compare the specified expectedResult with the result of formatting the specified value with the specified fmt obtained using a bslfmt::formatter specialization for the (template parameter) t_TYPE. If the specified alsoTestOracle is true, also compare the expectedResult with the result of formatting obtained using a standard library implementation. Optionally specify arg, arg1 and arg2 to be passed to the formatter as additional arguments. Return true if these strings are equal, otherwise store a description of the error in the specified output message and return false. Note that fmt is required to be a constant expression, known at compile time.

Return Value

true if formatting matches expectedResult, else false.

message

Output parameter for an error description on failure.
