When do you need to mock APIs? API mocking is typically used during development and testing as it allows you to build your app without worrying about 3rd party APIs or sandboxes breaking. What is API mocking? API mocking involves creating a simple simulation of an API, accepting the same types of request and returning identically structured responses as the real thing, enabling fast and reliable development and testing. For example, a user can clone a Git repository and build and test the program, automatically downloading newer versions of libraries where necessary, without interfering with the versions of those libraries installed by their distribution, which continue to be used for other software.FAQ What is WireMock? WireMock is a free API mocking tool that can be run as a standalone server, or in a hosted version via the WireMock Cloud managed service. The XML file describing the program’s requirements can also be included in a source-code repository, allowing full dependency handling for unreleased developer versions. Installation is always side-effect-free (each package is unpacked to its own directory and will not touch shared directories), making it ideal for use with sandboxing technologies and virtualization. For example, while it will share libraries whenever possible, it can always install multiple versions of a package in parallel when there are conflicting requirements.

Zero Install also has some interesting features not often found in traditional package managers. 0install packages never interfere with those provided by the distribution. It is intended to complement, rather than replace, the operating system’s package management. It allows software developers to publish programs directly from their own web-sites, while supporting features familiar from centralized distribution repositories such as shared libraries, automatic updates and digital signatures. Zero Install is a decentralized cross-platform software-installation system available under the LGPL.
