xtd::tunit::collection_assume Class Reference

Inheritance diagram for xtd::tunit::collection_assume:

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 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_assume::is_empty(list<int> {});
    }
    
    void test_method_(test_case2) {
      collection_assume::is_empty(list {1, 2, 3});
    }
    
    void test_method_(test_case3) {
      collection_assume::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)
//   ABORTED test.test_case2 (0 ms total)
//     Test aborted
//     Expected: <empty>
//     But was:  < 1, 2, 3 >

//   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.

static void xtd::tunit::collection_assume::is_not_empty ( const value_t &  value, const xtd::diagnostics::stack_frame &  stack_frame = xtd::diagnostics::stack_frame::current()  )

inlinestatic

Assumes that collection or traits does not contain any item.

Parameters

value	The value to check is empty.
stack_frame	Contains information about current file and current line.

Exceptions

xtd::tunit::abort_error

If bad assertion.

Examples

std::vector<int> v1 = {0, 1, 2, 3};
std::vector<int> v2;
xtd::tunit::collection_assume:is_not_empty(v1); // test ok.
xtd::tunit::collection_assume:is_not_empty(v2);// test throws an abort_error exception.

is_not_empty() [2/2]

template<typename value_t >

static void xtd::tunit::collection_assume::is_not_empty ( const value_t &  value, const std::string &  message, const xtd::diagnostics::stack_frame &  stack_frame = xtd::diagnostics::stack_frame::current()  )

inlinestatic

Assumes that collection or traits does not contain any item.

Parameters

value	The value to check is empty.
message	A user message to display if the assertion fails. This message can be seen in the unit test results.
stack_frame	Contains information about current file and current line.

Exceptions

xtd::tunit::abort_error

If bad assertion.

Examples

std::vector<int> v1 = {0, 1, 2, 3};
std::vector<int> v2;
xtd::tunit::collection_assume:is_not_empty(v1, "User message..."); // test ok.
xtd::tunit::collection_assume:is_not_empty(v2, "User message...");// test throws an abort_error exception.

is_ordered() [1/2]

template<typename value_t >

static void xtd::tunit::collection_assume::is_ordered ( const value_t &  value, const xtd::diagnostics::stack_frame &  stack_frame = xtd::diagnostics::stack_frame::current()  )

inlinestatic

Assumes that collection is ordered.

Parameters

value	The value to check is empty.
stack_frame	Contains information about current file and current line.

Exceptions

xtd::tunit::abort_error

If bad assertion.

Examples

std::vector<int> v1 = {1, 2, 3, 4};
std::vector<int> v2 = {1, 2, 4, 3};
xtd::tunit::collection_assume:is_ordered(v1); // test ok.
xtd::tunit::collection_assume:is_ordered(v2);// test throws an abort_error exception.
