Stack Moxie
Stack Moxie
Stack Moxie loves marketers. We are marketers. And we know that with technology - marketers can perform miracles. But marketers are setup to fail.

A CMO knows that the most cost-effective way to scale the business and enforce compliance is more technology. But a CTO would hesitate. She knows that marketers are missing one of the basic tools that IT can’t live without. A CTO would insist that the stack be tested. End to end, repeatedly. Are web forms functioning properly? Were the appropriate actions triggered by customer input? Can we pass an audit? For the marketer, these tools just don’t exist, nor does the time or budget to do this manually. That’s why we built Stack Moxie. Stack Moxie takes IT know-how and puts it into the hands of the marketer. We ensure martech works: leads aren’t lost, digital ad spend isn’t wasted, and when something breaks it won’t go unnoticedStarting Price: $99 per month -

Selenium
Software Freedom Conservancy
Selenium automates browsers. That's it! What you do with that power is entirely up to you. Primarily it is for automating web applications for testing purposes, but is certainly not limited to just that. Boring web-based administration tasks can (and should) also be automated as well. If you want to create robust, browser-based regression automation suites and tests, scale and distribute scripts across many environments, then you want to use Selenium WebDriver, a collection of language specific bindings to drive a browser - the way it is meant to be driven. If you want to create quick bug reproduction scripts, create scripts to aid in automation-aided exploratory testing, then you want to use Selenium IDE; a Chrome and Firefox add-on that will do simple record-and-playback of interactions with the browser. If you want to scale by distributing and running tests on several machines and manage multiple environments from a central point. -

Jasmine
Jasmine
Jasmine attempts as best as possible to follow semantic versioning. This means we reserve major versions (1.0, 2.0, etc.) for breaking changes or other significant work. Most Jasmine releases end up being minor releases (2.3, 2.4, etc.). Major releases are very infrequent. Jasmine generally avoids dropping support for browser or Node versions except in major releases. The exceptions to this are Node versions that are past end of life, browsers that we can no longer install locally and/or test against in our CI builds, browsers that no longer receive security updates, and browsers that only run on operating systems that no longer receive security updates. We’ll make reasonable efforts to keep Jasmine working in those environments but won’t necessarily do a major release if they break.Starting Price: Free -

Mocha
Mocha
Mocha runs in the browser. Every release of Mocha will have new builds of ./mocha.js and ./mocha.css for use in the browser. By adding an argument (usually named done) to it() to a test callback, Mocha will know that it should wait for this function to be called to complete the test. This callback accepts both an Error instance (or subclass thereof) or a falsy value; anything else is invalid usage and throws an error (usually causing a failed test). These reporters expect Mocha to know how many tests it plans to run before execution. This information is unavailable in parallel mode, as test files are loaded only when they are about to be run. In serial mode, tests results will “stream” as they occur. In parallel mode, reporter output is buffered; reporting will occur after each file is completed. In practice, the reporter output will appear in “chunks” (but will otherwise be identical). If a test file is particularly slow, there may be a significant pause while it’s running.Starting Price: Free -

PowerMock
PowerMock
Writing unit tests can be hard and sometimes good design has to be sacrificed for the sole purpose of testability. Often testability corresponds to good design, but this is not always the case. For example final classes and methods cannot be used, private methods sometimes need to be protected or unnecessarily moved to a collaborator, static methods should be avoided completely and so on simply because of the limitations of existing frameworks. PowerMock is a framework that extends other mock libraries such as EasyMock with more powerful capabilities. PowerMock uses a custom classloader and bytecode manipulation to enable mocking of static methods, constructors, final classes and methods, private methods, removal of static initializers and more. By using a custom classloader no changes need to be done to the IDE or continuous integration servers which simplifies adoption.Starting Price: Free -

Selenide
Selenide
You don't need to think how to shut down browser, handle timeouts and StaleElement Exceptions or search for relevant log lines, debugging your tests. We are proud to claim that Selenide is so simple that you don't need to read tons of documentation. Selenium WebDriver is a great tool, but it’s not a tool for testing. It’s a tool for browser manipulation. There are several testing libraries around Selenium WebDriver. But it seems that they do not resolve the main problems of UI tests. Namely, instability of tests caused by dynamic content, JavaScript, Ajax, timeouts etc. Selenide was created to resolve these problems. First of all, Selenide makes your tests stable by resolving (almost) all Ajax/timing issues. We are proud to claim that Selenide is so simple that you don't need to read tons of documentation. The whole work with Selenide consists of three simple things!Starting Price: Free -

Karma
Karma
The main goal for Karma is to bring a productive testing environment to developers. The environment being one where they don't have to set up loads of configurations, but rather a place where developers can just write the code and get instant feedback from their tests. Because getting quick feedback is what makes you productive and creative. Test your code on real browsers and real devices such as phones, tablets or on a headless PhantomJS instance. Control the whole workflow from the command line or your IDE - just save a file and Karma will run all the tests. Karma also watches all the files, specified within the configuration file, and whenever any file changes, it triggers the test run by sending a signal to the testing server to inform all of the captured browsers to run the test code again. Each browser then loads the source files inside an IFrame, executes the tests and reports the results back to the server.Starting Price: Free -

Deequ
Deequ
Deequ is a library built on top of Apache Spark for defining "unit tests for data", which measure data quality in large datasets. We are happy to receive feedback and contributions. Deequ depends on Java 8. Deequ version 2.x only runs with Spark 3.1, and vice versa. If you rely on a previous Spark version, please use a Deequ 1.x version (legacy version is maintained in legacy-spark-3.0 branch). We provide legacy releases compatible with Apache Spark versions 2.2.x to 3.0.x. The Spark 2.2.x and 2.3.x releases depend on Scala 2.11 and the Spark 2.4.x, 3.0.x, and 3.1.x releases depend on Scala 2.12. Deequ's purpose is to "unit-test" data to find errors early, before the data gets fed to consuming systems or machine learning algorithms. In the following, we will walk you through a toy example to showcase the most basic usage of our library. -

PHPUnit
PHPUnit
PHPUnit requires the dom and json extensions, which are normally enabled by default. PHPUnit also requires the pcre, reflection, and spl extensions. These standard extensions are enabled by default and cannot be disabled without patching PHP’s build system and/or C sources. The code coverage report feature requires the Xdebug (2.7.0 or later) and tokenizer extensions. Generating XML reports requires the xmlwriter extension. Unit Tests are primarily written as a good practice to help developers identify and fix bugs, to refactor code and to serve as documentation for a unit of software under test. To achieve these benefits, unit tests ideally should cover all the possible paths in a program. One unit test usually covers one specific path in one function or method. However a test method is not necessarily an encapsulated, independent entity. Often there are implicit dependencies between test methods, hidden in the implementation scenario of a test.Starting Price: Free
