ZK 6.5 (or later)
Introduction
About this article
nice application, how to test ... refer to zats... bla bla (marketing)
some things need to be tested in a real browser, so selenium comes into play... how to create tests
programmatically... link to older Small Talk?? or use Selenium-IDE to record/tweak/maintain!! and replay/debug -- this article :D
Environment
- Firefox (used with 21.0) - Selenium IDE 2.0.0 - JDK 6/7 - ZK 6.5.3 6/7 - Maven 3.0
Steps
Initialize your testing environment
- download Selenium IDE 2.0.0 link -- docu http://wiki.openqa.org/display/SIDE/Home - Maven 3.0 -- download link -- setup maven
- download link (test project) - maven: mvn jetty:run - localhost:8080 (- war file )
Initial Situation
launch Selenium IDE open example app record login-page and replay
- '(
nothing works...
look at the recorded commands
File:Changing ids.PNG ids are changing all the time,
IDGenerator
as mentioned in other smalltalks I use a custom IdGenerator to create predictable, readable (with a business meaning) and easily selectable (by selenium) component ids.
public class TestingIdGenerator implements IdGenerator {
...
}
In order not to mix up production with test configuration we can include an additional config file at startup to enable the TestingId enabled via java VMarg ... -Dorg.zkoss.zk.config.path=/WEB-INF/zk-test.xml
Windows set MAVEN_OPTS=-Dorg.zkoss.zk.config.path=/WEB-INF/zk-test.xml Linux export MAVEN_OPTS=-Dorg.zkoss.zk.config.path=/WEB-INF/zk-test.xml
mvn jetty:run
TODO: improve using maven profiles...
now we get nicer and deterministic IDs when recording the test
record login again
replay
still fails to replay why...
ZK heavily uses JavaScript and Selenium does not record all events by default
in our case here the "blur" events of the input fields have not been recorded, but ZK relies on them to determine possible dirty fields. So we need to manually add selenium commands "fireEvent target blur" unfortunately Selenium does not offer a nice equivalent like "focus"
File:Nicer ids with blur events.PNG
replay the script
- D now works, and we see the overview page ...
verify the page url, and some text on the page, to make sure the login redirects to the right page
Selenium Extensions
if you find it annoying to add an additional line just to update an input field there is a possible solution: custom Selenium extensions
This snipped shows a simple extension that combines the type with a blur event, to make ZK aware of the input change.
Selenium.prototype.doTypeAndBlur = function(locator, text) {
// All locator-strategies are automatically handled by "findElement"
var element = this.page().findElement(locator);
// Replace the element text with the new text
this.page().replaceText(element, text);
// Fire the "blur event"
triggerEvent(element, "blur", false);
};
user-extensions.js DOWNLOADable (file contains another extension ... more about that later in "making tests more robust and maintainable to UI updates")
add to Selenium IDE Options/Options... [General Tab] Selenium Core extensions
File:Nicer ids with implicit blur events.PNG
lets record a test for edit and save an existing "feedback item" in the list, and verify the results.
