Most of the interesting things happen in [./src/pinger.test.js](./src/pinger.test.js).
To run the tests:
- `npm install` (Node 10+, npm 6+)
- `npm test` to run tests (or `npm test -- --coverage` to run with coverage)
Note the use of `expect.anyting()` to ignore certain parameters to a function that aren't asserted against for specific tests.
```js
describe('without search', () => {
test('calls getPingConfigs with right accountId, searchRegex', async () => {
await pinger(1);
expect(mockPingConfig).toHaveBeenCalledWith(
1,
expect.anything(),
expect.anything(),
new RegExp('.*')
);
});
});
describe('offset, limit', () => {
test('calls getPingConfigs with passed offset and limit', async () => {
await pinger(1, { offset: 20, limit: 100 });
expect(mockPingConfig).toHaveBeenCalledWith(
1,
20,
100,
expect.anything()
);
});
test('calls getPingConfigs with default offset and limit if undefined', async () => {
await pinger(1);
expect(mockPingConfig).toHaveBeenCalledWith(1, 0, 50, expect.anything());
});
});
describe('search', () => {
describe('single-word search', () => {
test('calls getPingConfigs with right accountId, searchRegex', async () => {
await pinger(1, {}, 'search');
expect(mockPingConfig).toHaveBeenCalledWith(
1,
expect.anything(),
expect.anything(),
new RegExp('search')
);
});
});
describe('multi-word search', () => {
test('calls getPingConfigs with right accountId, searchRegex', async () => {
await pinger(1, {}, 'multi word search');
expect(mockPingConfig).toHaveBeenCalledWith(
1,
expect.anything(),
expect.anything(),
new RegExp('multi|word|search')
);
});
});
});
