Fix part of the test app and add new test util functions (#1977)
* fix: fix tests hanging because the console is not started * fix(@embark/proxy): send back errors correctly to the client Code originally by @emizzle and fixed by me * feat(@embark/test-runner): add assert.reverts to test reverts * fix: make test app actually run its test and not hang * fix(@embark/proxy): fix listening to contract event in the proxy * feat(@embark/test-runner): add assertion for events being triggered * docs(@embark/site): add docs for the new assert functions * feat(@embark/test-runner): add increaseTime util function to globals * docs(@embark/site): add docs for increaseTime

## Util functions
|
||||
|
||||
### assert.reverts
|
||||
|
||||
Using `assert.reverts`, you can easily assert that your transaction reverts.
|
||||
|
||||
```javascript
|
||||
await assert.reverts(contractMethodAndArguments[, options][, message])
|
||||
```
|
||||
|
||||
- `contractMethodAndArguments`: [Function] Contract method to call `send` on, including the arguments
|
||||
- `options`: [Object] Optional options to pass to the `send` function
|
||||
- `message`: [String] Optional string to match the revert message
|
||||
|
||||
Returns a promise that you can wait for with `await`.
|
||||
|
||||
```javascript
|
||||
it("should revert with a value lower than 5", async function() {
|
||||
await assert.reverts(SimpleStorage.methods.setHigher5(2), {from: web3.eth.defaultAccount},
|
||||
'Returned error: VM Exception while processing transaction: revert Value needs to be higher than 5');
|
||||
});
|
||||
```
|
||||
|
||||
### assert.eventEmitted
|
||||
|
||||
Using `eventEmitted`, you can assert that a transaction has emitted an event. You can also check for the returned values.
|
||||
|
||||
```javascript
|
||||
assert.eventEmitted(transaction, event[, values])
|
||||
```
|
||||
|
||||
- `transaction`: [Object] Transaction object returns by a `send` call
|
||||
- `event`: [String] Name of the event being emitted
|
||||
- `values`: [Array or Object] Optional array or object of the returned values of the event.
|
||||
- Using array: The order of the values put in the array need to match the order in which the values are returned by the event
|
||||
- Using object: The object needs to have the right key/value pair(s)
|
||||
|
||||
```javascript
|
||||
it('asserts that the event was triggered', async function() {
|
||||
const transaction = await SimpleStorage.methods.set(100).send();
|
||||
assert.eventEmitted(transaction, 'EventOnSet', {value: "100", success: true});
|
||||
});
|
||||
```
|
||||
|
||||
### increaseTime
|
||||
|
||||
This function lets you increase the time of the EVM. It is useful in the case where you want to test expiration times for example.
|
||||
|
||||
```javascript
|
||||
await increaseTime(amount);
|
||||
```
|
||||
|
||||
`amount`: [Number] Number of seconds to increase
|
||||
|
||||
```javascript
|
||||
it("should have expired after increasing time", async function () {
|
||||
await increaseTime(5001);
|
||||
const isExpired = await Expiration.methods.isExpired().call();
|
||||
assert.strictEqual(isExpired, true);
|
||||
});
|
||||
```
|
||||
|
||||
## Code coverage
|
||||
|
||||
Embark allows you to generate a coverage report for your Solidity Smart Contracts by passing the `--coverage` option on the `embark test` command.
