The document discusses various frontend testing methods including API tests, load tests, and layout tests, emphasizing tools like Postman and the Galen framework. It outlines testing techniques using scripts and environments for effective API management, along with automated layout testing for responsive design. Helpful links and resources are provided for deeper understanding and implementation of these testing strategies.

8. While working with APIs, you will often need to have
different setups. Environments give you the ability to
customize requests using variables.

11. Will help you to write API tests for your specific app logic
tests["Status code is 200"] = responseCode.code === 200;
var i = _.parseInt(environment.iteration);
if (i < 4) {
postman.setNextRequest("GettingName");
} else {
console.log("Finish ====");
postman.clearEnvironmentVariable("iteration");
postman.setNextRequest(null);
}

12. What else ?
● Pre-request scripts
● Integrated JS libs (lodash, tv4, …)
● Xml validation
● Console for debugging
● Import/export collections
● Convert data from
RAML/Swagger
● Proxy
● Data sync (Team account)
● Integrations (JIRA, Slack,
DataDog)

13. Monitors
Postman Monitors let you
easily test your APIs at
regularly-scheduled intervals.
You’ll be notified by email if
an API goes down or starts
misbehaving, and you can
track the status of your APIs
over time to spot trends and
potential problems.

22. Implementing Your Own Testing
Language
// homepage.gspec
button:
inside some_panel 0px left right
@rule %{elementName} stretches to %{parentName}
${elementName}:
inside ${parentName} 0px left right
| button stretches to some_panel
| submit_button, cancel_button are aligned horizontally next to each other with 20px margin

23. // Installing galen framework
npm install -g galenframework-cli
// Running our test from CLI
galen check homepage.spec --url http://testapp.galenframework.com/ --size 1024x768
How we can run our test ?
Galen relies on Selenium so it supports same browsers as
Selenium does. In order for galen to be able to communicate
with browser we need to get a special driver for it.

Galen Framework is designed with responsivness in mind. It is
easy to set up a test for different browser sizes. Galen just
opens a browser, resizes it to a defined size and then tests the
page according to specifications

26. LoginPage = $page("Login page", {
username: "input[name='login.username']",
password: "input[name='login.password']",
loginButton: "button.button-login"
loginAs: loggedFunction ("Log in as ${_1.username}", function(user) {
this.username.typeText(user.username);
this.loginButton.click();
})
});
test("Login page", function() {
var driver = createDriver("http://testapp.galenframework.com", "1024x768");
new LoginPage(driver).waitForIt();
checkLayout(driver, "loginPage.gspec", ["desktop"]);
});
