Test for +Bug 27514 - add support for watched expression. + +
To begin test, open web inspector, go the scripts panel +(enabling script debugging if necccessary), and then click this link: +[begin test]. + +
Perform the following steps, and note the expected results: + +
After clicking the link above, you should now be paused in the body of
+the test method, thanks to the debugger statement.
+
+
Add the following expressions to the "Watch Expressions" section of the
+Scripts panel sidebar pane: "this", "a",
+"b", "c" and "d". Do NOT enter the quotes.
+
+
The values of the expressions as shown in the window should a
+DOMWindow for this, undefined for
+the a, b, and c variables, and a
+value of ReferenceError: Can't find variable: d
+for the d variable.
+
+
Note that the value for d should not change for the life of
+the test, as the variable d is never introduced in the program.
+
+
Step through the code, and you'll see the values of a,
+b, and c change, as the variables are assigned.
+Also note that as the scope changes due to the function invocation, values
+will be changed to refer to their current scope. The this
+expression will change when the method is invoked on the object constructed by
+the test.
+
+
Click different stack frames in the Call Stack section to ensure the +expressions change value appropriately as the current stack frame changes. + +
Drive the debugger through the end of the outermost function, so that
+the debugger is no longer in paused state. The values of
+a, b, and c should all be a
+ReferenceError like d, since these variables are defined in the
+runTest() function, and the expressions are being evaluated against
+the global object.
+
+
From the console, execute the statement "a = 1". The
+watch expressions do not currently refresh, so the value for a
+should still be ReferenceError.
+
+
Click the "Refresh" button in the Watch Expressions section and the
+value for "a" should now be "1".
+
+
Close down the browser, start it back up, traverse to a web site, +bring up web inspector, go to the Scripts panel. You should see the same +set of Watch Expressions in the list as you had when you last used web +inspector. + +
Delete an expression by moving the mouse into the Watch Expression +section, and clicking the X icon which appears to the right of an +expression (on hover). + +
Delete an expression by double-clicking anywhere on a top-level line +of a watch expression, and changing the expression to an empty string or +nothing but white-space. + +
Modify an entry by double-clicking anywhere on a top-level line +of a watch expression, and changing the expression. + +
Enter a new expression, "new Date()". The value should be
+a toString() version of the date. Repeatedly press the Refresh button to see
+the value updated with the current time.
