Well-formed ZTL file

A ZTL file is a well-formed XML document.

For example,

<test import="java.util.*,java.io.*"
	browser="firefox,ie" tags="window">
	<case id="Method1">
		<server id="zulCode"><!--
			<button id="btn" label="click me" onClick='sayHi();'/>
		--></server>
		<server id="javaCode" lang="java"><![CDATA[
			vold sayHi() {
				alert("Hi!");
			}
		]]></server>
		<client>
			click(btn);
			waitResponse();
			verifyTrue(jq("@window").exists());
		</client>
	</case>
	<case id="Method2">
		<server ref="zulCode"/>
		<server lang="java"><!--
			void sayHi() {
				btn.detach();
			}
		--></server>
		<client>
			click(btn);
			waitResponse();
			verifyFalse(btn.exists());
		</client>
	</case>
</test>

As you can see, the content of the server is enclosed by <!-- --> or <![CDATA[ ]]>. The <!-- --> comment solves an issue which could arise if the content of the <server> tag contains another <![CDATA[ ]]> tag. You can choose either way to implement the server tag.

In addition, the content of the client tag is copied directly to the Java class which is generated, so the content should be valid Java. If the content contains the signs > or < (like in a for loop), you should use <![CDATA[ ]]> to enclose the content of the client for a well-formed ZTL file.

Each ID of the case in the ZTL file should be unique, for example, the case's ID maps to a method name of the Java class, therefore two methods with the same name should not be present in the same class. Moreover, the ID of the server is used to reference another server tag, so it is better to have different IDs to avoid unnecessary conflicts.


ID Naming Binding

Once you specify the ID of ZK component into the server tag, you can use the ID in the client tag directly.

For example,

<server>
	<button id="btn"/>
</server>
<client>
	click(btn);
</client>

or

<server lang="java">
	void createLabel(Window w) {
		Label label = new Label("Hello!");
		label.setId("mylabel");
		label.setParent(w);
	}
</server>
<client>
	verifyEquals("Hello!", getText(mylabel));
</client>

Scope Visibility

Please refer to the last sample.

Case

Each case tag has its own scope, so the content inside the case tag won't affect others.

Server

Each server tag can refer to another server tag which is placed in the same test tag (i.e. in the same ZTL file). Therefore you can use the ref property to refer to the other server tag for the same content.

Note: each server tag in the same case tag is run on the same ZK page via an Ajax request. Therefore the ID of the ZK component or the content of the Zscript may conflict if there is not another ID-Space-Owner.

Client

The content of each client tag in the same case will be copied to the same method of the java class so variable names should not be declared twice.


Utile API

Waiting Response

The API of waitResponse is employed when waiting for the response from the ZK server. For example, if you have a button to run Zscript at the ZK server and you have to check the value of another component after the process is done, you can invoke the waitResponse() method before checking the value.

For example,

click(btn); // it may cost some times.
waitResponse(); // ensure the process is done.
verifyEquals("Ready", label.get("value"));

Parse Integer from String

The parseInt function is employed to convert a string value into an int value.

For example, if the value of left is "125px", it will be converted into an integer of value 125.

JQuery jq = jq("@window");
int left = parseInt(jq.css("left"));
int top = parseInt(jq.css("top"));

Sleep the Current Thread

Because Thread.sleep() needs to try/catch the method, but the sleep() doesn't.

For example,

mouseOver(jq("$view @label:eq(2)"));
sleep(1000);
verifyTrue(jq("$mail div.z-popup-cm").exists());

Case Study

Checkbox

Check

You need to click the real sub-element, rather than invoking the check() method.

For example,

click(checkbox.$n("real"));

Combobox

Type

In combobox or bandbox, you need to “type” text into the real sub-element.

For example,

type(combobox.$n("real"), "abc");
verifyEquals("abc", msg.get("value"));

or

typeKeys(combobox.$n("real"), "abc");
verifyEquals("abc", msg.get("value"));

Note: the typeKeys will simulate the event in order keyDown, keyPress, and keyUp.

Spinner/Timebox

Click

In the two widgets, you have to use mouseDownAt/mouseUp() instead of clickAt().

For example,

mouseDownAt(jq("@spinner i.z-spinner-btn"), "0,0");
mouseUp(jq("@spinner i.z-spinner-btn"));
blur(jq("@spinner i.z-spinner-btn"));
verifyTrue(5 < parseInt(jq("@spinner input.z-spinner-inp").val()));
mouseDownAt(jq("@spinner i.z-spinner-btn"), "3,20");
mouseUp(jq("@spinner i.z-spinner-btn"));
blur(jq("@spinner i.z-spinner-btn"));
verifyTrue(3 > parseInt(jq("@spinner input.z-spinner-inp").val()));
  • You have to use blur(), otherwise it will not save the value to server.

Menu

Click right arrow

You need to click the arrow area of the menu. For example,

<server><!--
	<zk>
		<menubar>
			<menu label="click me" onClick="">
				<menupopup>
					<menuitem label="item" onClick='alert("you click")' />
				</menupopup>
			</menu>
		</menubar>
	</zk>
--></server>
<client>
	JQuery menu = jq("@menu[label=\"click me\"]");
	clickAt(menu, ""+(menu.width() - 5)+",5");
</client>

Menupopup

Right Click

You need to use contextMenu, rather than invoking the mouseDownRight() method.

For example,

contextMenu(jq("@image"));

Tree

Open

In treeitem, you have to click upon the open sub-element.

For example,

click(treeitem.$n("open"));

Window

Drag Drop

In the overlapped window or modal window, you need to drag the element upon the cap sub-element.

For example,

dragdropTo(jq("@window > div[id$=\"cap\"]"), "10,10", "160,160");

As you can see, the selector matches a any div with an id ending with cap inside a window component.

Textbox

Copy and Paste

In textbox, you can use keyDownNative, keyPressNative and keyUpNative to execute ctrl + A, ctrl + X, ctrl + C and ctrl + V.

For example,

focus(jq("@textbox"));

keyDownNative("17");
keyPressNative("65");
keyPressNative("88");
keyPressNative("86");
keyUpNative("17");
  • keycode:
  1. Ctrl: 17
  2. A: 65
  3. V: 86
  4. X: 88
  • Note: You have to call keyUpNative("17"); when you call keyDownNative("17");, otherwise your compute will keep hold ctrl key.

Troubleshooting

Escaping Single Quotation

You may use the jQuery's selector to find a ZK or other elements within the client tag.

For example,

verifyTrue(jq("@window[border=\"normal\"]").exists());

As you can see, you need to use the " double quotation rather than single quotation in this case as Selenium will translate the content to enclose with a single quotation.

Test without Server tag

Sometimes you will need to test the zul file directly from ZK server. Thus, you can modify the action property to the path of the zul file. For example.
