Anay Nayak Organization: ThoughtWorks Topic: Fluent interfaces in testing Presented in vodQA - THE TESTING SPIRIT! on Oct 7, 2010 in ThoughtWorks, Pune

1. Fluent Interfaces in Testing

2. @Test
public void testCheckResults() {
startSeleniumSession("localhost", 8000, "firefox", "www.google.com");
Selenium selenium = session();
selenium.type("//input[@name="search"]", "vodQA infusion");
selenium.click("//form[@id='search']/a/span[text()='Go']");
selenium.waitForPageToLoad("300000");
selenium.isElementPresent("//div[@class='resultStats']");
verifyTrue(session().isTextPresent("the testing spirit"));
}

3. @Test
public void shouldReturnResultsForGivenQuery() {
new HomePage()
.enterSearchString("vodQA infusion").search()
.validateResultsDisplayed()
.validateSearchResult("the testing spirit");
}

@Test
public void testCheckResults() {
startSeleniumSession("localhost", 8000, "firefox", "www.google.com");
Selenium selenium = session(); selenium.type("//input[@name="search"]",
"vodQA infusion");
selenium.click("//form[@id='search']/a/span[text()='Go']");
selenium.waitForPageToLoad("300000");
selenium.isElementPresent("//div[@class='resultStats']");
verifyTrue(session().isTextPresent("the testing spirit"));
}

5. Fluent Interface?
@Test
public void shouldReturnResultsForGivenQuery() {
new HomePage()
.enterSearchString("vodQA infusion").search()
.validateResultsDisplayed()
.validateSearchResult("the testing spirit"); }

7. Confused?

8. A different example
import static org.openqa.selenium.lift.Finders.*;
import static org.openqa.selenium.lift.Matchers.*;
...
@Test
public void testHasAnImageSearchPage() {
goTo("http://www.google.com");
assertPresenceOf(link("Images"));
assertPresenceOf(atLeast(4), links().with(text(not(equalTo("Images")))));
clickOn(link("Images"));
assertPresenceOf(title().with(text(equalTo("Google Image Search"))));
}

9. assertThat

10. Examples
assertThat(searchResultsCount, greaterThan(10));
assertThat(username, equalTo("Anay"));
assertThat(currentTimeText, startsWith("Local time:"));
assertThat(basket, new IsCollectionContaining<String>(equalTo("apples")));
assertThat(xml, hasXPath("/root/@type", equalTo("food")));
