Writing a simple test
A simple test in Google Test can be written using the TEST macro, which defines a test function. Within this function, you can use various assertions to verify the behavior of your code. Here’s a basic example:
#include <gtest/gtest.h>
int add(int a, int b) {
return a + b;
}
TEST(AdditionTest, HandlesPositiveNumbers) {
EXPECT_EQ(5, add(2, 3));
}
In this example, EXPECT_EQ is used to assert that the add function returns the expected sum of two positive numbers. Google Test provides a variety of assertions such as EXPECT_GT (greater than), EXPECT_TRUE (Boolean true), and many others for different testing scenarios.
The key difference between EXPECT_* and ASSERT_* assertions lies in their behavior upon failure. While EXPECT_* assertions allow the test to continue running after a failure, ASSERT_* assertions will halt the current test function immediately upon failure. Use EXPECT_* when subsequent...
