如何使用UnitTest ++运行单个测试?
我正在运行UnitTest ++。我的main
函数如下所示:
int main()
{
printf("diamond test v0.1 %s\n\n",TIMESTAMP);
diamond::startup();
UnitTest::RunAllTests();
diamond::shutdown();
printf("press any key to continue...");
getc(stdin);
}
对于调试,我想写一些像UnitTest::RunSingleTests("MyNewUnitTest");
而不是UnitTest::RunAllTests();
的东西。 UnitTest ++是否提供了这样的功能?若然,语法是什么?

尝试将其作为unittest的main()(我实际上把它放在一个文件中并将其添加到unittest库中,这样当链接到库时,可执行文件会自动使用这个main()。非常方便。)
int main( int argc, char** argv )
{
if( argc > 1 )
{
//if first arg is "suite", we search for suite names instead of test names
const bool bSuite = strcmp( "suite", argv[ 1 ] ) == 0;
//walk list of all tests, add those with a name that
//matches one of the arguments to a new TestList
const TestList& allTests( Test::GetTestList() );
TestList selectedTests;
Test* p = allTests.GetHead();
while( p )
{
for( int i = 1 ; i < argc ; ++i )
if( strcmp( bSuite ? p->m_details.suiteName
: p->m_details.testName, argv[ i ] ) == 0 )
selectedTests.Add( p );
p = p->next;
}
//run selected test(s) only
TestReporterStdout reporter;
TestRunner runner( reporter );
return runner.RunTestsIf( selectedTests, 0, True(), 0 );
}
else
{
return RunAllTests();
}
}
使用参数调用以运行单个测试:
> myexe MyTestName
或单一套件
> myexe suite MySuite

这几乎是正确的。 “测试”实际上是作为链接列表中的节点,因此当您将其添加到新列表时,您必须更正指针以避免包含比您预期更多的测试。
所以你需要更换
p = p->next;
与
Test* q = p;
p = p->next;
q->next = NULL;

如果你告诉它名字,RunTestsIf只能运行一个套件。
class MyTrue
{
public:
MyTrue(const std::string & suiteName, const std::string & testName)
: suite(suiteName), test(testName) {}
bool operator()(const UnitTest::Test* const testCase) const
{
return suite.compare(testCase->m_details.suiteName) == 0 &&
test.compare(testCase->m_details.testName) == 0;
}
private:
std::string suite;
std::string test;
};
int main (...) {
bool isSuite = false;
std::string suiteName = "suite01";
std::string testName = "test01";
UnitTest::TestReporterStdout reporter;
UnitTest::TestRunner runner(reporter);
if (isSuite) {
runner.RunTestsIf(UnitTest::Test::GetTestList(),
NULL, MyTrue(suiteName, testName), 0);
} else {
runner.RunTestsIf(UnitTest::Test::GetTestList(),
NULL, UnitTest::True(), 0);
}
}

您可以使用predicate
的{{1}}参数:
RunTestsIf
如果您没有套件,或者想要搜索所有套件,则可以将TestReporterStdout reporter;
TestRunner runner(reporter);
return runner.RunTestsIf(Test::GetTestList(), "MySuite",
[](Test* t) {
return strcmp(t->m_details.testName, "MyTest") == 0;
}, 0);
替换为"MySuite"
。

@stijn给出的答案在测试列表操作中有一个错误,因此它通常会运行您未请求的其他测试。
此示例使用谓词仿函数,并且还利用RunTestsIf提供的内置套件名称匹配。这是正确的,也更简单。
#include "UnitTest++.h"
#include "TestReporterStdout.h"
#include <string.h>
using namespace UnitTest;
/// Predicate that is true for tests with matching name,
/// or all tests if no names were given.
class Predicate
{
public:
Predicate(const char **tests, int nTests)
: _tests(tests),
_nTests(nTests)
{
}
bool operator()(Test *test) const
{
bool match = (_nTests == 0);
for (int i = 0; !match && i < _nTests; ++i) {
if (!strcmp(test->m_details.testName, _tests[i])) {
match = true;
}
}
return match;
}
private:
const char **_tests;
int _nTests;
};
int main(int argc, const char** argv)
{
const char *suiteName = 0;
int arg = 1;
// Optional "suite" arg must be followed by a suite name.
if (argc >=3 && strcmp("suite", argv[arg]) == 0) {
suiteName = argv[++arg];
++arg;
}
// Construct predicate that matches any tests given on command line.
Predicate pred(argv + arg, argc - arg);
// Run tests that match any given suite and tests.
TestReporterStdout reporter;
TestRunner runner(reporter);
return runner.RunTestsIf(Test::GetTestList(), suiteName, pred, 0);
}

接受的答案中的解决方案对我不起作用。当套件的第一次测试加载到p中时,它就不会跳到下一个测试(不知道确切原因)。
我正在使用Xcode和UnitTest ++ v1.4
#include "UnitTest++.h"
#include "TestReporterStdout.h"
#define SUITE_NAME "ActionFeedback"
using namespace UnitTest;
int main( int argc, char** argv )
{
#ifdef SUITE_NAME
TestReporterStdout reporter;
TestRunner runner( reporter );
return runner.RunTestsIf( Test::GetTestList() , SUITE_NAME , True(), 0 );
#else
return RunAllTests();
#endif
}
