This section presents several test suites for different boundary conditions. This section introduces several test suites for different boundary conditions based on the get_triangle_area() function. It takes two filenames as a parameter, one for the length of the base of the triangle and one for its height. It reads each line and calculates the correct area of the triangle for each line.

  floats, and each of its elements is a calculated area. Test suite below:

  Code Block
  language cpp title TEST(GetTriangleArea, CheckType) linenumbers true
  TEST(GetTriangleArea, CheckType) { std::string height_file = "triangle_height.txt"; std::string base_file = "triangle_base.txt"; EXPECT_EQ(typeid(std::vector<float>), typeid(get_triangle_area(base_file, height_file))); }

  The function under test is quite complex and takes up a lot of lines, so there's no room for it here, but it's worth learning how it works. In this test suite, it is important to provide valid file names, use typeid() to determine the argument type, and use the EXPECT_EQ assertion to verify that it is the same as vector<float>.
