## Build the Docker image
docker build -t btroops .
## Install packages
./npm install
## Start the dev server
./npm run start
Visit `localhost:8080` to view.
## Run integration tests
./npm run test:integ
### Debugging an integration test
1. Put `debugger` in whatever test you want to debug.
2. Add `only` to the test's `it` function call.
From `it(...` to `it.only(...`.
3. Then run `./npm run test:integ:debug` to start start the debugger.
```
> test:integ:debug
> NODE_INSPECT_RESUME_ON_START=1 node inspect ./node_modules/jest/bin/jest.js --config jest.config.integ.cjs --runInBand test/integration/page.test.js
< Debugger listening on ws://127.0.0.1:9229/7150f5fc-339a-4171-af42-b8902d0d3e31
< For help, see: https://nodejs.org/en/docs/inspector
<
connecting to 127.0.0.1:9229 ... ok
< Debugger attached.
<
< Jest config file read.
<
<

<
<
break in test/integration/page.test.js:31
29 counter = await driver.findElement(By.css(selector), svg);
30 await counter.click();
>31 debugger;
32 expect(await counter.getAttribute('class')).toEqual(expect.stringContaining('selected'));
33 });
debug>
```
4. To run the test again without having to quit the debugger, use `c` to continue past the breakpoint and then `r` to restart.
```
debug> c
...
<
< Stopping server.
<
< Waiting for the debugger to disconnect...
<
```
```
debug> r
