是否有更好的解决方案来使用 Google 测试框架测试 getter

Question

I am testing the getters of a class. Each getter has some regex code to validate the input.

I use the Google Test Framework to write the unit tests.

Every time I want to test a new getter I need to expand the parameters of the constructor. I need to update the code of the previous tests to not break the previous tests.

Like this:

TEST_F(wsRecordTest,DoesItThrowExceptionWhenWrongCitynameIsProvided)
{
    weatherdayRecord wsRecord{"!#Delft$*"}; --> has to be: weatherdayRecord wsRecord{"!#Delft$*","2020-10-03"}; 
    ASSERT_THROW(wsRecord.getCity(),std::invalid_argument);
}

// Test accessor getDate() and constructor
TEST_F(wsRecordTest,DoIGetTheRightDateFromTheConstructor)
{
    weatherdayRecord wsRecord{"Delft","2020-10-03"};
    ASSERT_EQ(wsRecord.getDate(),"2020-10-03");
}

Is there a way to avoid this?

Answer 1

How about adding a SetUp functionality to your fixture?

class wsRecordTest : public ::testing::Test {
    protected:
        std::unique_ptr<weatherdayRecord> record;
        void SetUp() override {
            record = std::make_unique<weatherdayRecord>("Delft", "2020-10-03");
        }
}

TEST_F(wsRecotdTest, CheckDate) {
     ASSERT_EQ(record->getDate(), "2020-10-03");
}

Not sure though why you want to test your getters if the classes are just holders for data..
