Definition

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

Namespace: xtd::tunit

Library: xtd.tunit

Remarks: Assumptions are intended to express the state a test must be in to provide a meaningful result. They are functionally similar to assertions, however a unmet assumption will produce an aborted test result, as opposed to a failure.

Examples: This example show how to used some methods :
#include <xtd/xtd.tunit>
using namespace std;
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) {
collection_assume::is_empty(vector<int> {});
}

void test_method_(test_case2) {
collection_assume::is_empty(vector<int> {1, 2, 3});
}

void test_method_(test_case3) {
collection_assume::is_ordered(vector<int> {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 test.test_case1 (0 ms total)
// ABORTED test.test_case2 (0 ms total)
// Test aborted
// Expected: <empty>
// But was: < 1, 2, 3 >
// Stack Trace: in |---OMITTED---|/collection_assume.cpp:14
// ABORTED test.test_case3 (0 ms total)
// Test aborted
// Expected: < 1, 2, 3 >
// But was: < 1, 3, 2 >
// Stack Trace: in |---OMITTED---|/collection_assume.cpp:18
//
// Test results:
// SUCCEED 1 test.
// ABORTED 2 tests.
// End 3 tests from 1 test case ran. (0 ms total)
