I was using Mocha to test my Nodejs app with a test database. In order to reset the DB before each test I had the following code, which worked perfectly:
process.env.NODE_ENV = 'test';
var knex = require('../db/knex');
describe("Add Item", function() {
beforeEach(function(done) {
knex.migrate.rollback()
.then(function() {
knex.migrate.latest()
.then(function() {
return knex.seed.run()
.then(function() {
done();
});
});
});
});
...
I've since switched from mocha to mocha-casperjs for my integration tests, and now the knex migrations won't run. I'm given this error message with the exact same before each hook:
undefined is not an object (evaluating 'knex.migrate.rollback')

I'm pretty sure that migration functionality is not included in webpack build. If you go to http://knexjs.org/ open up debug console and checkout different clients e.g. mysql.migrate you see that there are no functions declared at all.
Actually you can check it out with node too if you explicitly load webpack build instead of node lib.
// load webpack build instead of node build...
let knex = require('knex/build/knex')({client : 'pg'});
console.log(knex.migrate);
// outputs: {}
So... the question is why are you trying to run your tests on PhantomJS browser instead of node.js?

I am running into an issue where I am running multiple tests using supertest and jest. When there is only one test running then it works just fine but the second one throws the following error:
ReferenceError: You are trying to `import` a file after the Jest environment has been torn down.
I tested this with two very simple tests:
describe("Default API", () => {
describe("Default:", () => {
it("should create a user in the DB", (done) => {
request(app).get("/").expect(200, done);
});
it("should create a user in the DB", (done) => {
request(app).get("/").expect(200, done);
});
});
});
They are the same but the second one throws the error. If I run only the first one there is no issue. This must be a setup issue Does anyone have advice. In my index.ts where I have the main express code I export app as follows:
export default app;
This is at the bottom of the index.ts file.
I had the simular problem and toggle down the issue, in my case I want to use mysql2 to access mariadb. That Module try to autodetect the charset and do to try to lacy loading that encoding.
But I have not found a solution for that for now.
I'm using Quasar framework and just after I've added quasar-dotenv package I realized that e2e tests not working.
Uncaught TypeError: fs.readFileSync is not a function
This error originated from your test code, not from Cypress.
When Cypress detects uncaught errors originating from your test code it will automatically fail the current test.
Cypress could not associate this error to any specific test.
We dynamically generated a new test to display this failure.

I've tried to set up the Cypress environment by adding the test/cypress/plugins/cypress.env.json file with some data, as well as changing the test/cypress/plugins/index.js file in the same folder, by following this documentation as it was suggested here:
const env = require('quasar-dotenv').config()
module.exports = (on, config) => {
// config.env.API_URL = 'http://example.com' // not working
config.env = env
// Chrome:: Hack for shaking AUT. Cypress Issue: https://github.com/cypress-io/cypress/issues/1620
on('before:browser:launch', (browser = {}, args) => {
if (browser.name === 'chrome') {
args.push('--disable-blink-features=RootLayerScrolling');
return args;
}
return true;
});
return config
};
MacOS Catalina
Cypress v3.5.0
Chrome v77
I don't know the answer because I am unfamiliar with quasar-dotenv. Have you tried the official quasar dotenv app extension? https://github.com/quasarframework/app-extension-dotenv or, alternatively, another official app extension, but less opinionated than dotenv wrappers: https://github.com/quasarframework/app-extension-qenv
I have NestJs application with TypeORM configured with mysql. I want to have e2e(integration) test and for that reason I want to have in memory database in the tests which I configured this way:
{
type: 'sqlite',
database: ':memory:',
synchronize: true,
dropSchema: true,
entities: [`dist/**/*.entity{.ts,.js}`],
}
And the setup of the tests
beforeEach(async () => {
const moduleFixture: TestingModule =
await Test.createTestingModule({imports: [AppModule, UserModule]})
.overrideProvider(TypeOrmConfigService).useClass(MockTypeOrmConfigService)
.compile();
app = await moduleFixture.createNestApplication();
await app.init();
});
. When running the test I got
AlreadyHasActiveConnectionError: Cannot create a new connection named "default", because connection with such name already exist and it now has an active connection session.

(node:19140) UnhandledPromiseRejectionWarning: AlreadyHasActiveConnectionError: Caught error after test environment was torn down
If I move the setup from beforeEach in beforeAll block it's ok, but I'm afraid that when I create several specs the error will come back. How should be handled properly?
EDIT:
The problem was that each test is making a setup of the application and so creates a new connection.The solution was to use "keepConnectionAlive: true," in order all tests to reuse same connection.
keepCOnnectionAlive: true is the way to go
Using keepConnectionAlive: true produced the following error for me.
Jest did not exit one second after the test run has completed.
This usually means that there are asynchronous operations that weren't
stopped in your tests. Consider running Jest with
--detectOpenHandles to troubleshoot this issue.
Adding the below to each e2e test fixed my issue:
afterEach(async () => {
await app.close();
});
Base on 0xCAP's answer, you can do something like this also.
// jest.setup.ts
jest.mock("/path/to/database/config/object", () => {
const { databaseConfig, ...rest } = jest.requireActual("/path/to/database/config/object")
return {
...rest,
databaseConfig: {
...databaseConfig,
keepConnectionAlive: true // replace old config
}
}
})
// jest.config.js
module.exports = {
...other options
setupFilesAfterEnv: ["jest.setup.ts"],
}
I find myself writing this at the start of pretty much all of my unit tests in mocha:
it('should do something', (done) => {
Vue.config.errorHandler = done;
// do something aynchronous
});
By default, Vue catches all errors itself and logs them to the console, so mocha can't see them. This code makes sure that thrown errors fail the tests.
Is there a way with mocha to do this without having to start every single async test with this line of code? If I have to write / use a plugin, that's fine.
Try:
Vue.config.errorHandler = function (err, vm, info) {
throw err
}
in your test entry.
Running the following jasmine test under webdriver.io like this: node path/to/test/script.js, the test executes (web browser is pulled up, target page visited), and thanks to the last line, the jasmine 'it' functions (below) do execute (without the last line, they don't, although the 'describe' function still runs).
But jasmine doesn't provide any kind of report result for the 'it' tests and the 'expect' assertions; there's nothing on the console from jasmine. There's no 'pass/fail' result, and so forth.
How to get jasmine to make a report, and esp. one that is readable by Jenkins?
The problem test script:
var webdriverjs = require('foo-bar/node_modules/webdriverio');
var jasmine = require('foo-bar/node_modules/jasmine-node');
var options = {
port: 4445,
desiredCapabilities: {
browserName: process.argv[2] || 'phantomjs'
}
};
describe('my webdriverjs tests', function () {
var client;
jasmine.DEFAULT_TIMEOUT_INTERVAL = 9999999;
beforeEach(function() {
client = webdriverjs.remote(options);
client.init();
});
it('shows the correct title', function (done) {
client
.url('http://localhost:4444').getTitle(function(err, title) {
expect(title).toBe('foo bar');
}).call( done );
});
afterEach(function(done) {
client.end(done);
});
});
jasmine.getEnv().execute();
Note: Cross-posted here: https://groups.google.com/forum/#!topic/webdriverio/-EOrQ003B9I
I ran into some of the same challenges when I was looking into this. The big issue is that this test needs to be executed as a jasmine test, not a webdriver test.
decribe('my webdriverio tests with jasmine', function(){
var client;
beforeEach(function(){
client = require('path/to/webdriverio').remote({
desiredCapabilities: {browserName:'safari'}
}).init.url('https://www.stackoverflow');
}, 5000);
afterEach(function(done){
client.end(done);
}, 5000);
it('runs a very simple test',function(done){
client.getTitle(function(err,result){
expect(result).toBe('Stack Overflow');
}).call(done);
}, 5000);
});
Now to run this test, you would just run a typical jasmine-node command from your terminal.
It comes down to the naming convention you are using. First, you need to remove the last line: jasmine.getEnv().execute(); then run the jasmine-node command with the --matchall flag:
jasmine-node --matchall path/to/test/script.js
If you named your file script_spec.js, then you could run it without the --matchall flag.
This is also assuming you have jasmine-node installed globally. If you want to use the local node_modules dependency, then you need to run this command:
./node_modules/jasmine-node/bin/jasmine-node --matchall path/to/test/script.js
When you are using jasmine-node module you should run your spec with
node_modules/jasmine-node/bin/jasmine-node $TEST_DIRECTORY
And your test should end with *spec.js, *spec.coffee or *spec.litcoffee as docs said.
And jasmine.getEnv().execute(); and var jasmine = require('foo-bar/node_modules/jasmine-node'); should not be in your script.
