[英]How do I run a test with multiple sets of initial conditions?
I currently have a suite of tests which are are part of a test fixture.我目前有一套测试,它们是测试装置的一部分。 I want to run the same set of tests with a different test fixture too.我也想用不同的测试夹具运行相同的测试集。
How do I do this without actually having to copy-paste the tests and 'manually' changing the test fixture name (as shown below)?如何在不实际复制粘贴测试和“手动”更改测试夹具名称的情况下执行此操作(如下所示)?
class Trivial_Test : public ::testing::Test
{
void SetUp()
{
ASSERT_TRUE(SUCCESS == init_logger());
initial_condition = 0;
}
void TearDown()
{
shutdown_logger();
}
protected:
int initial_condition;
};
class Trivial_Test_01 : public ::testing::Test
{
void SetUp()
{
ASSERT_TRUE(SUCCESS == init_logger());
initial_condition = 1;
}
void TearDown()
{
shutdown_logger();
}
protected:
int initial_condition;
};
TEST_F(Trivial_Test, valid_input_1)
{
EXPECT_TRUE(random_num()+initial_condition < 255);
}
TEST_F(Trivial_Test_01, valid_input_1)
{
EXPECT_TRUE(random_num()+initial_condition < 255);
}
Is there a less verbose way of associating valid_input_1
with both Trivial_Test
and Trivial_Test_01
?是否有一种将valid_input_1
与Trivial_Test
和Trivial_Test_01
相关联的不那么冗长的方法?
PS - The test case shown above is a trivial test which nominally represents my actual situation but nowhere close to the complexity of the testcases or testfixtures I am actually dealing with. PS - 上面显示的测试用例是一个微不足道的测试,它名义上代表了我的实际情况,但远不及我实际处理的测试用例或测试夹具的复杂性。
Did you consider value parameterized tests ?您是否考虑过值参数化测试?
Maybe for your actual test cases it adds too much complexity, but your example would look like:也许对于您的实际测试用例,它增加了太多的复杂性,但您的示例看起来像:
class Trivial_Test : public ::testing::TestWithParam<int>
{
void SetUp()
{
ASSERT_TRUE(SUCCESS == init_logger());
}
void TearDown()
{
shutdown_logger();
}
};
TEST_F(Trivial_Test, valid_input)
{
int initial_condition = GetParam();
EXPECT_TRUE(random_num()+initial_condition < 255);
}
INSTANTIATE_TEST_CASE_P(ValidInput,
Trivial_Test,
::testing::Values(0, 1));
You can do this using a method in a fixture class.您可以使用夹具类中的方法来执行此操作。 Here is how you would do this for you example:以下是您将如何为您执行此操作的示例:
class Trivial_Test : public ::testing::Test
{
void SetUp()
{
ASSERT_TRUE(SUCCESS == init_logger());
}
void TearDown()
{
shutdown_logger();
}
setup_initial_condition(int value)
{
initial_condition = value;
}
protected:
int initial_condition;
};
TEST_F(Trivial_Test, valid_input_1)
{
setup_initial_condition(0);
EXPECT_TRUE(random_num()+initial_condition < 255);
}
TEST_F(Trivial_Test, valid_input_2)
{
setup_initial_condition(1);
EXPECT_TRUE(random_num()+initial_condition < 255);
}
