* Basic pytest configuration * Added unit_test script that triggers pytest * Changed "fixtures" to fixture_path This is consistent with pytest's tmp_path * Initial unit tests for esphome.helpers * Disabled coverage reporting for esphome/components. Focus initial unittest efforts on the core code. * Migrated some ip_address to hypothesis * Added a hypothesis MAC address strategy * Initial tests for core * Added hypothesis to requirements * Added tests for core classes TestTimePeriod Lambda ID DocumentLocation DocumentRange Define Library * Updated test config so package root is discovered * Setup fixtures and inital tests for pins * Added tests for validate GPIO * Added tests for pin type * Added initial config_validation tests * Added more tests for config_validation * Added comparison unit tests * Added repr to core.TimePeriod. Simplified identifying faults in tests * Fixed inverted gt/lt tests * Some tests for Espcore * Updated syntax for Python3 * Removed usage of kwarg that isn't required * Started writing test cases * Started writing test cases for cpp_generator * Additional docs and more Python3 releated improvements * More test cases for cpp_generator. * Fixed linter errors * Add codegen tests to ensure file API remains stable * Add test cases for cpp_helpers
