I'm trying to test a simple form using Selenium, WebDriver.io & Node.js (with Mocha). So I have something like this:
var webdriverio = require('webdriverio');
var expect = require('expect');
describe('Test form', function(){
beforeEach(function() {
browser.url('/');
});
it('should save object', function() {
expect(browser.executeScript('return window.data;')).to.be([]);
});
afterEach(function() {
if (this.currentTest.state !== "passed") {
browser.saveScreenshot();
}
});
});
My wdio.conf.js
:
var selenium = require('selenium-standalone');
var seleniumServer;
exports.config = {
host: '127.0.0.1',
port: 4444,
specs: [
'test/*.spec.js'
],
capabilities: [{
browserName: 'chrome'
}],
baseUrl: 'http://localhost:8080',
framework: 'mocha',
mochaOpts: {
ui: 'bdd'
},
onPrepare: function() {
return new Promise((resolve, reject) => {
selenium.start((err, process) => {
if(err) {
return reject(err);
}
seleniumServer = process;
resolve(process);
})
});
},
onComplete: function() {
seleniumServer.kill();
}
};
But in console I have: browser.executeScript is not a function
. What is the right way to execute script in browser context using these tools?
Okay, I was searching in sources and find /build/lib/protocol/execute.js
. Example from there:
client.execute(function(a, b, c, d) {
// browser context - you may not access neither client nor console
return a + b + c + d;
}, 1, 2, 3, 4).then(function(ret) {
// node.js context - client and console are available
console.log(ret.value); // outputs: 10
});
But now all commands in wdio are synchronous (proof issue). So the right way for me is:
var data = browser.execute(function() {
return window.data;
});
expect(data.value).to.be([]);
/* note, here ^ is a property with value of execution */
