Testing our Conan package

Once Conan builds our package, it should test whether it was properly built. In order to do so, let's start by creating a test_package subdirectory in our conan directory.

It will also contain a conanfile.py script, but this time a shorter one. It should start as follows:

import os
 
from conans import ConanFile, CMake, tools
 
 

class CustomerTestConan(ConanFile):
     settings = "os", "compiler", "build_type", "arch"
     generators = "CMakeDeps"

Nothing too fancy here. Now, we should provide the logic to build the test package:

    def build(self):
        cmake = CMake(self)
        # Current dir is "test_package/build/<build_id>" and 
        # CMakeLists.txt is in "test_package"
        cmake.configure()
        cmake.build()

We'll write our CMakeLists.txt file in a sec. But first, let's write two more things: the imports method and the test method. The imports method can be...
