Why can't CircleCi find my tests? - testing

Question

Please see repo structure below. I want to run the tests in root/app2/tests/. I am using py.test.
After CircleCi couldn't infer test directory automatically I added a circle.yml file to the root directory but still the tests are not found. Any help greatly appreciated.
circle.yml file content:
general:
build_dir: app2/tests
Repository structure:
root
├── circle.yml
├── app1
│ ├── xxx
│ ├── yyy
│
└── app2
├── src
├── tests
|-- test_module_1.py
|-- test_module_2.py

Answer 1

Ok with help from CircleCI I figured out how to use py.test with CircleCI:
In the circle.yml file add:
test:
override:
- py.test <optional path to subdir with tests>
dependencies:
pre:
- pip install pytest
If your code relies on several packages in addition to py.test, you can create a requirements.txt file:
pip freeze > requirements.txt
place the requirements.txt file in the same directory as the circle.yml file (or in the build_dir if you have specified that in your circle.yml file) and add to circle.yml:
dependencies:
pre:
- pip install -r requirements.txt

It’s generally enough to set the build_dir to just the application directory, we’ll take care of finding the tests subdirectory ourselves.
Could you please try replacing your current command in the circle.yml with this?
general:
build_dir: app2
