Hands-on browser automation

SeLite makes Selenium better

SeLite automates browser navigation and testing. It extends Selenium. It

SeLite enables DB-driven navigation with SQLite (the most widely deployed SQL database).


SeLite enables the following in Selenium IDE

Data separation (in testing)

Some application errors cause incorrect data that doesn’t show up on the immediate screens (or not at all during the same session). Such defects present themselves only on subsequent screens or even much later (through their knock-on effect). Having a test DB (in SQLite) isolated from the application’s DB facilitates early detection of those bugs.

Separation allows validation of the data as presented by the application anytime later, rather than just right after the data was updated. So in addition to checking the immediate pages within the same test run, this also checks the application continually, taking any previous operations into account (including previous sessions). If the application shared its database with the test, such defects would be difficult or even impossible to detect.

See illustrations at TestMethods and details at TestMethodsTheory.


SeLite is easy to install, with no server side (apart from the controlled web application itself). You need Firefox and Components (Selenium IDE and components of SeLite family). You may want some AddOnsThirdParty.

See Compatibility regarding Opera and Chrome.


When using complex scripts you need a framework. Several come with SeLite and are listed at AppsFrameworks. Follow InstallFramework and any framework-specific steps. Read PackagedScripts on how to run demos. See also Customisation below.


Scripts (whether for testing or not) can store their data in SQLite database. When used for testing, test DB is initialised to a copy (or an export) of the web application’s DB.


When customising or creating frameworks or components for Selenium IDE, following topics can assist you:



Quality is ensured by


SeLite is compatible with Firefox 48 and Selenium IDE 2.9.1. It’s platform-independent. (It doesn’t support Flash/Silverlight/ActiveX.) Its part SelBlocks Global is mostly forward compatible with SelBlocks 2.0.1.

Currently it doesn’t operate with browsers other than Firefox. However, in 2017 Firefox extensions will use the same API as Opera and Chrome.

SeLite is not for Selenium WebDriver. Effectiveness and convenience of Selenium IDE together with SeLite can, however, outweigh WebDriver. For detailed comparison see WhySeleniumIDE.

SeLite is fully open source. Most Components are under GNU LGPL 3.

You could get more out of SeLite. However, it depends on third party components. To help it progress, please would you
