Write Test

When you create a processor through the command line, it will automatically generate a basic jest test for you.
test('has valid config', async () => {
const config = await service.getConfig({})
expect(config.contractConfigs.length > 0).toBeTruthy()
})
It simply starts the processor and checks if there is any basic error that failed the processor declaration.
To check the logic of your handler function, we can use testLog , testBlock, testTrace , to send events to your processor. In the code we generated for your contract, there are also some test utils that help you generate mocked data. Below is a test example that mocks a transfer event, sends it to the processor, and verifies the result :
import { TestProcessorServer, firstCounterValue } from '@sentio/sdk/testing'
import { mockTransferLog } from '@sentio/sdk/eth/builtin/erc20'
describe('Test Processor', () => {
const service = new TestProcessorServer(() => import('./processor.js'))
beforeAll(async () => {
await service.start()
})
test('check transfer event handling', async () => {
const resp = await service.testLog(
mockTransferLog('0x1e4ede388cbc9f4b5c79681b7f94d36a11abebc9', {
from: '0x0000000000000000000000000000000000000000',
to: '0xb329e39ebefd16f40d38f07643652ce17ca5bac1',
value: 10n ** 18n * 10n,
})
)
const tokenCounter = firstCounterValue(resp.result, 'token')
expect(tokenCounter).toEqual(10n)
})
})
