 ## Unit Tests
 
+### PHP
+
 For unit tests of the php code the folder `tst/` can be used. Apart from helping to implement new features correctly it helps to keep regressions at bay. By default a code coverage report is generated after phpunit is run, the one of the latest release is [publicly](https://codeclimate.com/github/PrivateBin/PrivateBin/coverage) [available](https://www.codacy.com/app/PrivateBin/PrivateBin/files).

 * phpunit
-* php5-gd
+* php-gd
-* php5-sqlite
+* php-sqlite3
-* php5-xdebug
+* php-xdebug (for code coverage reports)
 
-Example installation for Debian and Ubuntu:
+Example for Debian and Ubuntu:
+```console
+$ sudo apt install phpunit php-gd php-sqlite php-xdebug
+```
 
-    $ sudo aptitude install phpunit php5-mysql php5-xdebug
+To run the tests, just change into this directory and run phpunit:
+```console
+$ cd PrivateBin/tst
+$ phpunit
+```
 
-To run the tests, just change into the `tst/` directory and run phpunit:
+Additionally there is the `ConfigurationTestGenerator`. Based on the configurations defined in its constructor, it generates the unit test file `tst/ConfigurationCombinationsTest.php`, containing all possible combinations of these configurations and test for (most) valid combinations. Some of combinations can't be tested with this method, i.e. a valid option combined with an invalid one. Other very specific test cases (i.e. to trigger multiple errors) are covered in `tst/PrivateBinTest.php`. Here is how to generate the configuration test and run it:
 
     $ cd PrivateBin/tst
-    $ phpunit
+    $ php ConfigurationTestGenerator.php
-
+    $ phpunit ConfigurationCombinationsTest.php

-    $ cd PrivateBin/tst
-    $ php configGenerator.php
-    $ phpunit configuration.php
 
 Note that it can take an hour or longer to run the several thousand tests.
 
+### JavaScript
+
+For unit tests of the JS code the folder `js/` can be used. Apart from helping to implement new features correctly it helps to keep regressions at bay. By default a code coverage report is generated after istanbul is run.
+
+In order to run these tests, you will need to install the following packages
+and its dependencies:
+* npm
+
+Then you can use the node package manager to install the latest stable release
+of mocha and istanbul (for code coverage reports) globally and jsVerify, jsdom
+and jsdom-global locally:
+
+```console
+$ npm install -g mocha istanbul
+$ cd PrivateBin/js
+$ npm install jsverify jsdom jsdom-global
+```
+
+Example for Debian and Ubuntu, including steps to allow current user to install
+node modules globally:
+```console
+$ sudo apt install npm
+$ sudo mkdir /usr/local/lib/node_modules
+$ sudo chown -R $(whoami) $(npm config get prefix)/{lib/node_modules,bin,share}
+$ ln -s /usr/bin/nodejs /usr/local/bin/node
+$ npm install -g mocha istanbul
+$ cd PrivateBin/js
+$ npm install jsverify jsdom jsdom-global
+```
+
+To run the tests, just change into the `js` directory and run istanbul:
+```console
+$ cd PrivateBin/js
+$ istanbul cover _mocha
+```

 ## Data Model
 
 If you want to create your own data models, you might want to know how the arrays, that you have to store, look like:
