LeetTest — bombtastic

Stop hand-writing testcases. LeetTest generates fresh random inputs for the LeetCode problem you're on and pastes them straight into the Testcase tab, so you can hit Run and see how your solution handles cases you didn't think of.

WHAT IT DOES

★ One-click random testcases
Open a problem, click Generate Testcases, and LeetTest fills the Testcase tab with 8 new cases in the problem's input format. It switches to the Testcase tab and Source view for you, even if LeetCode left you on Test Result.

★ Numeric difficulty ratings
"Medium" covers a lot of ground. LeetTest adds a contest-based numeric rating next to Easy / Medium / Hard (for example "Medium - 1486"), so you know how hard a problem really is. Problems without a rating show "Not found".

★ Company tags
See which companies have asked the problem, right under the title, without LeetCode Premium.

★ Your settings
Hide difficulty entirely to practice without bias, or turn the numeric rating and company tags on and off. Changes apply to open LeetCode tabs instantly.

★ Report bad testcases in two clicks
Generators are built per problem, and occasionally one misses a constraint. If a set looks wrong, hit the report button and pick what went wrong. Reported problems get their generator rebuilt, so every report makes it better for everyone.

Works on Chrome and Firefox.

PRIVACY
LeetTest has no accounts and never reads your code. To fetch ratings and testcases, it sends only the name of the problem you're viewing (for example "two-sum") and the extension version to the LeetTest server. Reports send the problem name and the reason you picked. Your settings stay in your browser.
