Question

Eclipse Juno Service Release 1

Example of a working Unit Test …

InRangeTest = TestCase("InRangeTest");

InRangeTest.prototype.test01 = function()
{
    var ir = new InRange(0.0, "<", Number.MAX_VALUE, "≤");
    assertTrue(ir.isInRange(0.3));
};

But, to do more than one test I believe I should be using setUp. Unless I am mistaken, the advantage of setUp is that I would not have to instantiate var ir in every unit test. So, I tried the following …

InRangeTest = TestCase("InRangeTest");

InRangeTest.prototype.setUp = function()
{
    var ir = new InRange(0.0, "<", Number.MAX_VALUE, "≤");
};

InRangeTest.prototype.test01 = function()
{
    assertTrue(ir.isInRange(0.3));
};

Only, I get the error message

ReferenceError: ir is not defined

Replacing var ir with this.ir did not get it working.

What’s wrong?

Thanks for any help in advance.

If you use this.ir in both functions it should work:

InRangeTest = TestCase("InRangeTest");

InRangeTest.prototype.setUp = function()
{
    this.ir = new InRange(0.0, "<", Number.MAX_VALUE, "≤");
};

InRangeTest.prototype.test01 = function()
{
    assertTrue(this.ir.isInRange(0.3));
};
