Inheritance diagram for xtd::tunit::collection_assert:

Definition

The collection_assert class contains a collection of static methods that implement the most collection 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>

using namespace xtd::collections::generic;

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) {

collection_assert::is_empty(list<int> {});

}

void test_method_(test_case2) {

collection_assert::is_empty(list {1, 2, 3});

}

void test_method_(test_case3) {

collection_assert::is_ordered(list {1, 3, 2});

}

};

}

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: <empty>

// But was: < 1, 2, 3 >

// Stack Trace: in |---OMITTED---|/collection_assert.cpp:14

// FAILED unit_tests::test.test_case3 (0 ms total)

// Expected: < 1, 2, 3 >

// But was: < 1, 3, 2 >

// Stack Trace: in |---OMITTED---|/collection_assert.cpp:18

//

// Test results:

// SUCCEED 1 test.

// FAILED 2 tests.

// End 3 tests from 1 test case ran. (0 ms total)
