Testium is a testing platform focused on providing a simple, but effective, platform for testing your code in different browsers (via Selenium) and headlessly (via PhantomJS). It uses webdriver-http-sync in order to communicate using the WebDriver protocol to a selenium server.
A simple test using assertive.
{getBrowser} = require 'testium'
assert = require 'assertive' # or whatever assert library you prefer
describe 'browse', ->
before ->
@browser = getBrowser()
@browser.navigateTo '/my-account'
@browser.assert.httpStatus 200
it 'is serving up gzipped content', ->
assert.equal 'gzip', @browser.getHeader('Content-Encoding')
For help debugging your tests, check out the wiki page.
On Ubuntu, you need to make sure you have libcurl installed.
sudo apt-get install libcurl4-openssl-dev
If you want to use the experimental image diffing,
you must have libpng installed.
sudo apt-get install libpng-dev
If you see execvp(): No such file or directory
,
you may not have java installed.
You can install OpenJDK or JDK 7.
Install Testium by adding "testium": "~1.0.0"
to your package.json
and running npm install
.
Then, you need to require it and run it, like so!
testium = require 'testium'
testOptions =
beforeTests: "#{__dirname}/test/setup.coffee" # custom test setup script
tests: "#{__dirname}/test/integration" #string or array of absolute and/or directory paths and/or glob patterns
applicationPort: 4000
screenshotDirectory: "#{__dirname}/test/failed_screenshots"
browser: 'phantomjs' # chrome | firefox
appDirectory: "#{__dirname}/.." # allows relative paths to files/dirs to test
seleniumServer: 'http://localhost:9999/wd/hub' # optional external selenium server
javaHeapSize: 256 # optional max java heap size; in megabytes
http:
timeout: 60000
connectTimeout: 20000
mochaOptions:
reporter: 'spec'
timeout: 20000
slow: 4000
testium.run testOptions, (error, exitCode) ->
# handle result
If the seleniumServer
option is not specified,
the first test run will download
the latest selenium standalone server
and chromedriver.
Testium provides an interactive CoffeeScript console as a bin stub. It creates a browser and mixes the methods of that browser into the global scope.
You can use it like so!
$ ./node_modules/.bin/testium
%> navigateTo 'google.com'
%> element = getElement 'input[name="q"]'
%> element.type 'puppies\n'
And the browser will navigate to google.com
,
find the search box,
and type puppies\n
into it.
You should now see search results for puppies.
This is useful for testing out your commands before setting up an actual test.
browser = getBrowser()
Method | Description |
---|---|
browser.navigateTo(url, options) |
Navigates the browser to the specificed relative or absolute url. If relative, the root is assumed to be http://127.0.0.1:#{applicationPort} , where applicatioAnPort is passed in to the options for testium.runTests . options can include a headers param with headers to pass along with the request. |
browser.refresh() |
Refresh the current page. |
browser.getElement(cssSelector) |
Finds an element on the page using the cssSelector and returns an Element. |
browser.getElements(cssSelector) |
Finds all elements on the page using the cssSelector and returns an array of Elements. |
browser.waitForElement(cssSelector, timeout=3000) |
Waits for the element at cssSelector to exist and be visible. Times out after timeout ms. |
browser.getUrl() |
Returns the current url ('http://localhost:1234/some/route') of the page. |
browser.waitForUrl(url, timeout=5000) |
Waits timeout ms for the browser to be at the specified url . |
browser.getPath() |
Returns the current path ('/some/route') of the page. |
browser.waitForPath(path, timeout=5000) |
Waits timeout ms for the browser to be at the specified path . |
browser.getPageTitle() |
Returns the current page title. |
browser.getPageSource() |
Returns the current page's html source. |
browser.getScreenshot() |
Returns screenshot as a base64 encoded PNG. |
browser.click(cssSelector) |
Calls Click on the Element found by the given cssSelector . |
browser.type(cssSelector, keys...) |
Sends keys... to the input Element found by the given cssSelector . |
browser.clear(cssSelector) |
Clears the input Element found by the given cssSelector . |
browser.clearAndType(cssSelector, keys...) |
Clears the input Element found by the given cssSelector , then sends keys... to it. |
browser.evaluate(javascriptString) |
Executes the given javascript. It must contain a return statement in order to get a value back. |
browser.evaluate(function) |
Returns the result of the given function, invoked on the webdriver side (so you can not bind its this object or access context variables via lexical closure). |
browser.evaluate(args..., function(args...)) |
Same as above, but marshals the args as JSON and passes them to the function in the given order. E g: browser.evaluate 'hash', (prop) -> window.location[prop] would return the current url fragment. |
browser.setCookie(Cookie) |
Sets a cookie on the current page's domain. Cookie = { name, value, path='/' } |
browser.setCookies([Cookie]) |
Sets all cookies in the array. Cookie = { name, value, path='/' } |
browser.getCookie(name) |
Returns the cookie visible to the current page with name . |
browser.getCookies() |
Returns all cookies visible to the current page. |
browser.clearCoookies() |
Deletes all cookies visible to the current page. |
browser.getStatusCode() |
Returns the response status code for the current page. |
browser.getHeader(name) |
Returns the value of the response header with the provided name. |
browser.getHeaders() |
Returns all response headers for the current page. |
browser.close(callback) |
Closes the Testium session. |
Method | Description |
---|---|
browser.alert.getText() |
Gets the text of a visible alert, prompt, or confirm dialog. |
browser.alert.accept() |
Accepts a visible alert, prompt, or confirm dialog. |
browser.alert.dismiss() |
Dismisses a visible alert, prompt, or confirm dialog. |
browser.alert.type(keys...) |
Types into a visible prompt dialog. |
Note: Alerts effectively don't work when running with PhantomJS.
getText()
will throw an error and the others will just silently not work.
If you must test with PhantomJS you can work around this by
stubbing the alert
, confirm
, and prompt
global methods
in your client-side javascript.
Below is an example.
# Stub alert
@browser.evaluate 'return window.alert = function() { };'
# Stub confirmation
desiredValue = true
@browser.evaluate "return window.confirm = function() { return #{desiredValue}; };"
# Stub prompt
desiredValue = 'foo'
@browser.evaluate "return window.prompt = function() { return \'#{desiredValue}\'; };"
Method | Description |
