Cookie Validation

In order to provide the handling of HTTP cookies for developers, ZATS Mimic introduces a group of methods on Client. ZATS Mimic seamlessly maintains cookies after connecting with a ZK application. It can read the current cookies and verify the behaviors of the ZK application. Following is a typical example of cookie validation:

cookie.zul

<zk>
	<div apply="CookieComposer">
		<button id="change" label="change" />
	</div>
</zk>


CookieComposer.java

public class CookieComposer extends SelectorComposer<Component> {
	public void doAfterCompose(Component comp) throws Exception {
		super.doAfterCompose(comp);
		setCookie("foo", "bar");
	}

	@Listen("onClick=#change")
	public void change() {
		setCookie("foo", "hello");
	}

	public void setCookie(String name, String value) {
		HttpServletResponse resp = (HttpServletResponse)Executions.getCurrent().getNativeResponse();
		resp.addCookie(new Cookie(name, value));
	}
}
  • Line 13: This will add a cookie at the beginning.
  • Line 16, 18: Changes the cookie from server-side when the user clicks the button.


Test.java

@Test
public void Test() {
	Client client = Zats.newClient();
	DesktopAgent desktop = client.connect("/cookie.zul");
	Assert.assertEquals("bar", client.getCookie("foo"));
	Assert.assertEquals(null, client.getCookie("not existed"));
	desktop.query("#change").click();
	Assert.assertEquals("hello", client.getCookie("foo"));
}
  • Line 13-15: After connecting to a ZUL page, we can get the cookies and verify them.
  • Line 16-17: ZATS Mimic maintains all cookies during any operations.

Set Cookie in a Test Case

Usually, developers use cookies to retain some information between individual connections. For example, it can trace activities of users or remember some useful information for users. ZATS Mimic allows us to add, change or remove cookies through the Client which comes in very handy for testing the above cases. Following is a simple example on using a cookie to remind a user of his/her last read page number:

cookie.zul

<zk>
	<div apply="CookieComposer">
		<label id="msg" value="first time reading" />
	</div>
</zk>
  • Line 3: Reminds user of his/her last read page number here.


CookieComposer

public class CookieComposer extends SelectorComposer<Component> {
	@Wire
	private Label msg;
	
	public void doAfterCompose(Component comp) throws Exception {
		super.doAfterCompose(comp);
		Execution exec = Executions.getCurrent();
		Cookie[] cookies = ((HttpServletRequest)exec.getNativeRequest()).getCookies();
		if(cookies != null) {
			for(Cookie cookie : cookies) {
				if("page".equals(cookie.getName()))
					msg.setValue("last read page: " + cookie.getValue());
			}
		}
	}
}
  • Line 20-21: This will show the last read page according to the cookie stored at client-side.


Test.java

@Test
public void test() {
	Client client = Zats.newClient();
	client.setCookie("page", "99");
	DesktopAgent desktop = client.connect("/cookie.zul");
	String msg = desktop.query("#msg").as(Label.class).getValue();
	Assert.assertEquals("last read page: 99", msg);
}
  • Line 12-14: We can append a new cookie before connecting with a page for testing.
