Test of an unobtainable value in JSSpec

I am learning JSSpec. Here's my problem.

In this code :

describe("Buttons' events", {

'when I click on a button with an id of #b1...': function() {
    click_me(document.getElementById("b1"));
},

'...then URL should have a parameter b with the value someURL1 and a parameter ui with the value 527bd5b5d689e2c32ae974c6229ff785), because #b1\'s class is .testme': function() {
    value_of(observer.URLforTests_lg).should_match(/http:\/\/swkyb\.com:9000/);
    value_of(observer.URLforTests_lg).should_match(/ui=527bd5b5d689e2c32ae974c6229ff785/);
    value_of(observer.URLforTests_lg).should_match(/b=someURL1/);
    value_of(observer.URLforTests_lg).should_match(/s=tester/);
    value_of(observer.URLforTests_lg).should_match(/e=button/);
    value_of(observer.URLforTests_lg).should_match(/api=testv/);
}

I don't understand where the value 527bd5b5d689e2c32ae974c6229ff785 in observer.URLforTests_lg).should_match(/ui=527bd5b5d689e2c32ae974c6229ff785/); comes from. I have looked for this String on my project but I don't find where it is defined (if so).

Resolved: 527bd5b5d689e2c32ae974c6229ff785 is just the md5 code for john, which is in the project configuration files.
