Inheritance diagram for xtd::tunit::file_valid:
xtd::tunit::base_assert

Definition

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

Namespace
xtd::tunit
Library
xtd.tunit
Remarks
Validations are the same as assertions with the difference, no exception is thrown, but an error is generated.
If a validation fails, he test can be continued to the end or to an assertion is generated.
Examples
This example show how to used some methods :
#include <xtd/xtd.tunit>
#include <stdexcept>
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) {
void test_method_(test_case1) {
auto fn = path::get_temp_file_name();
file_valid::exists(fn);
file::remove(fn);
}
void test_method_(test_case2) {
auto fn = path::get_random_file_name();
file_valid::exists(fn);
// No need to remove fn because the file does not exist.
}
void test_method_(test_case3) {
auto is = std::istringstream {"xtd::tunit::file_valid::are_equal example."};
file_valid::are_equal(std::istringstream {"xtd::tunit::file_valid::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 unit_tests::test.test_case1 (0 ms total)
// FAILED unit_tests::test.test_case2 (0 ms total)
// Expected: file exists
// But was: "t35uk5my.8v2"
// Stack Trace: in |---OMITTED---|/file_valid.cpp:18

// Expected: istream at offset 31 value e
// But was: a
