# Local testing
|
||
|
|
|
||
|
|
## Unit & integration tests
|
||
|
|
|
||
|
|
To run tests:
|
||
|
|
|
||
|
|
```
|
||
|
|
make test
|
||
|
|
```
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
Also test watcher can be launched. It will re-run the entire test suite when any file is modified
|
||
|
|
|
||
|
|
```
|
||
|
|
make test-watch
|
||
|
|
```
|
||
|
|
|
||
|
|
Developers can also manually change the shadow-cljs option `:ns-regex` to control which namespaces the test runner should pick.
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
## Testing with REPL
|
||
|
|
|
||
|
|
The most convenient way to develop and run test locally is using REPL:
|
||
|
|
|
||
|
|
1. Run command `make test-watch-for-repl`.
|
||
|
|
3. Once you see the message `[repl] shadow-cljs - #3 ready!` you can connect a REPL to the `:test` target from VS Code, Emacs, etc.
|
||
|
|
4. In any test namespace, run [cljs.test/run-tests](https://cljs.github.io/api/cljs.test/#run-tests) or your preferred method to run tests in the current namespace.
|
||
|
|
|
||
|
|
You can run single test in REPL like this
|
||
|
|
|
||
|
|
```clojure
|
||
|
|
(require 'cljs.test)
|
||
|
|
(cljs.test/test-var #'status-im.data-store.chats-test/normalize-chat-test)
|
||
|
|
```
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
Tests will use the bindings in `modules/react-native-status/nodejs`, if you make any changes to these you will need to restart the watcher.
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
### Example in Emacs
|
||
|
|
|
||
|
|
In the video below, you can see two buffers side-by-side. On the left the source implementation, on the right the REPL buffer. Whenever a keybinding is pressed, **tests in the current namespace instantly run**. You can achieve this exact flow in VS Code, IntelliJ, Vim, etc.

### Example in terminal emulator
|
||
|
|
|
||
|
|
Here I'm showing a terminal-only experience using Tmux (left pane Emacs, right pane the output coming from running the make target).
