Browser Cache

I recently udpated our Jasmine unit tests to run in Karma ; expanding our browser coverage, adding code coverage reports , and using fixtures for testing DOM manipulation . One of my tests kept failing in IE9, but only when I ran from the console. If I attempted to debug in the browser, everything passed. It turns out that IE9 (at least) needed a few ms to catch it's breath before correctly focusing on the starting element. To do this, I just added a 100ms delay before each test ran (Using Jasmine 2.3). beforeEach(function(done){ loadFixtures('myfixture.html'); // Setting focus in IE requires a delay to work correctly! setTimeout(function(){ done(); }, 100); });
