Definition

The file_assert class contains a collection of static methods that implement the most file assertions used in xtd::tUnit.

Namespace: xtd::tunit

Library: xtd.tunit

Remarks: Assertions are central to unit testing in any of the xUnit frameworks, and xtd.tunit is no exception. xtd.tunit provides a rich set of assertions as static methods of the Assert class.; If an assertion fails, the method call does not return and an error is reported. If a test contains multiple assertions, any that follow the one that failed will not be executed. For this reason, it's usually best to try for one assertion per test.; Each method may be called without a message, with a simple text message or with a message and arguments. In the last case the message is formatted using the provided text and arguments.

Examples: This example show how to used some methods :
#include <xtd/xtd.tunit>
#include <stdexcept>
using namespace std;
using namespace xtd::io;
using namespace xtd::tunit;
namespace unit_tests {
// The class test must be declared with test_class_ helper.
class test_class_(test) {
public:
void test_method_(test_case1) {
auto fn = path::get_temp_file_name();
file_assert::exists(fn);
file::remove(fn);
}

void test_method_(test_case2) {
auto fn = path::get_random_file_name();
file_assert::exists(fn);
// No need to remove fn because the file does not exist.
}

void test_method_(test_case3) {
auto is = istringstream {"xtd::tunit::file_assert::are_equal example."};
file_assert::are_equal(istringstream {"xtd::tunit::file_assert::are_equel example."}, is);
}
};
}
auto main()->int {
return console_unit_test().run();
}
// This code can produce the following output:
//
// Start 3 tests from 1 test case
// Run tests:
// SUCCEED test.test_case1 (0 ms total)
// FAILED test.test_case2 (0 ms total)
// Expected: file exists
// But was: "t35uk5my.8v2"
// Stack Trace: in |---OMITTED---|/file_assert.cpp:18
// FAILED test.test_case3 (0 ms total)
// Expected: istream at offset 32 value e
// But was: a
// Stack Trace: in |---OMITTED---|/file_assert.cpp:24
//
// Test results:
// SUCCEED 1 test.
// FAILED 2 tests.
// End 3 tests from 1 test case ran. (0 ms total)

template<typename char_t >

static void xtd::tunit::file_assert::does_not_exist	(	const std::basic_string< char_t > &	file,
		const std::string &	message,
		const xtd::diagnostics::stack_frame &	stack_frame
	)

inlinestatic

Asserts that file not exists.

Parameters

expected	the expected value.
