Bug 11579 – Fix test script error when checking the correct result.

• Component: JavaScriptCore
• Status: RESOLVED DUPLICATE

in tests/mozilla/js1_2/version120/boolean-001.js, the test script check the Bollean object by using RelationalExpression directly:

object = new Bollean(false);
if (object) {
   // is true
} else {
   // is false
}

Though the object value is false, but the IF statement will apply ToBollean operator (ECMA 9.3) with Object, and return true always. To fix this, simply use "EqualityExpression == RelationalExpression" in the IF statement instead:

object = new Bollean(false);
if (object == true) {
   // is true
} else {
   // is false
}

correct the expected results

Is this really a mistake in the test, or a bug in our engine?

I'm wondering why this test passed in Spider Monkey and Rhino.

huh, I tried SpiderMonkey before, it's failed. Here's the result of SpiderMonkey (lastest cvs build)

boolean-001.js new Boolean(false) should evaluate to false
new Boolean(true) = true PASSED!
new Boolean(false) = true FAILED! expected: false
true = true PASSED!
false = false PASSED!

At least based on ECMA spec., the ToBoolean(Object) will always return true, and we are acting same with SpiderMonkey on this.

Is this the same as bug 4263? Please note the difference between this test and js1_3/Boolean/boolean-001.js.

Yes, same with bug 4263, but what they are talking about is not the cause, ther really cause that failed the test was the comment I described on the top.

And if you check js1_3/Boolean/boolean-001.js, you will note that they were expected "new Boolean(false)"  to return true when using RelationalExpression directly (js1.6 does same way):

BooleanTest( "new Boolean(false)", new Boolean(false), true );

Since JavaScriptCore is not planning on support the early specification, we would suggest to ignore and disable this js1.2 test.

OK, so I'm r-'ing the attached patch, as it does something different.
