Algebraic laws for regular expressions can be obtained using a method by Gischer which is best explained along an example: In order to check whether (X+Y) ∗ and (X ∗ Y ∗) ∗ denote the same regular language, for all regular expressions X, Y, it is necessary and sufficient to check whether the particular regular expressions (a+b) ∗ and ...
A regexp interprets all metacharacters. Testing a regexp pattern responsibly, requires limiting the search domain by making it a single page using a page-name filter prefix:page name; a prefix parameter or other filter that limits the search domain to only as many pages as necessary; the test wiki.
Jasmine is an open-source testing framework for JavaScript. [4] It aims to run on any JavaScript-enabled platform, to not intrude on the application nor the IDE , and to have easy-to-read syntax. It is heavily influenced by other unit testing frameworks, such as ScrewUnit, JSSpec, JSpec, and RSpec .
For example, a bare namespace returns the pages of the namespace. The query term1 term2 regexp relies heavily on the first two terms to reduce the search domain size. All terms in a query are indexed searches unless they are a regexp. Indexed terms run word-wise instantly, and a regexp runs character-wise slowly. Even the most basic use of a ...
A JUnit test runner that runs JavaScript tests. The goal of the JS Test Runner is to be able to test JavaScript code using an approach that test driven programmers will feel comfortable with; particularly in the context of Continuous Integration. Sinon.js: Compatible: Yes: Yes [237] Standalone test spies, stubs and mocks for JavaScript.
Mocha is a JavaScript test framework for Node.js programs, featuring browser support, asynchronous testing, test coverage reports, and use of any assertion library. [ 2 ] Assertion libraries
When using AWB, you can refresh the typo list by selecting "File → Refresh status/typos" (CTRL-R). This is useful when you are modifying the typo list on Wikipedia while using AWB to test/process the modification (but basic testing should first be done offline—e.g. by using AWB's Regex Tester or "Find and replace").
