Clear Firefox cache in Selenium IDE

Question

I'm using Selenium IDE to test a web application. Sometimes my tests succeed even though they should have failed. The reason is that the browser happens to load a previous version of a page from the cache instead of loading the newer version of that page. In other words, I might introduce a bug to my app without being aware of it because the tests may pass after loading a previous working version instead of loading the new buggy version.

The best solution I could have thought of is to delete the browser cache before running the tests. I have a Selenium script in which I run set-up selenium commands before running the tests. Is there a selenium command to clear Firefox cache? Alternatively, is there another way to prevent loading pages from the cache during the tests?

Answer 1

In python this should disable firefox cache:

profile = webdriver.FirefoxProfile()
profile.set_preference("browser.cache.disk.enable", False)
profile.set_preference("browser.cache.memory.enable", False)
profile.set_preference("browser.cache.offline.enable", False)
profile.set_preference("network.http.use-cache", False)
driver = webdriver.Firefox(profile)

hope this helps someone

You can disable the cache in firefox profile. See this link for more details.

Answer 3

For those programming in Java, here is how I solve the issue:

    FirefoxProfile profile = new FirefoxProfile();
    profile.setPreference("browser.cache.disk.enable", false);
    profile.setPreference("browser.cache.memory.enable", false);
    profile.setPreference("browser.cache.offline.enable", false);
    profile.setPreference("network.http.use-cache", false);
    FirefoxOptions options = new FirefoxOptions().setProfile(profile);
    driver = new FirefoxDriver(options);
