 Tests
 -----
-If your PR is a feature (ie. if it's being labelled with the 'T-Enhancement'
-label) then we require that the PR also includes tests. These need to test that
-your feature works as expected and ideally test edge cases too. For the js-sdk
-itself, your tests should generally be unit tests. matrix-react-sdk also uses
-these guidelines, so for that your tests can be unit tests using
-react-test-utils, snapshot tests or screenshot tests.
+Your PR should include tests.
 
-We don't require tests for bug fixes (T-Defect) but strongly encourage regression
-tests for the bug itself wherever possible.
+For new user facing features in `matrix-react-sdk` or `element-web`, you
+must include:
 
-In the future we may formalise this more with a minimum test coverage
-percentage for the diff.
+1. Comprehensive unit tests written in Jest. These are located in `/test`.
+2. "happy path" end-to-end tests.
+   These are located in `/test/end-to-end-tests` in `matrix-react-sdk`, and
+   are run using `element-web`. Ideally, you would also include tests for edge
+   and error cases.
+
+Unit tests are expected even when the feature is in labs. It's good practice
+to write tests alongside the code as it ensures the code is testable from
+the start, and gives you a fast feedback loop while you're developing the
+functionality. End-to-end tests should be added prior to the feature
+leaving labs, but don't have to be present from the start (although it might
+be beneficial to have some running early, so you can test things faster).
+
+For bugs in those repos, your change must include at least one unit test or
+end-to-end test; which is best depends on what sort of test most concisely
+exercises the area.
+
+Changes to `matrix-js-sdk` must be accompanied by unit tests written in Jest.
+These are located in `/spec/`.
+
+When writing unit tests, please aim for a high level of test coverage
+for new code - 80% or greater. If you cannot achieve that, please document
+why it's not possible in your PR.
+
+Tests validate that your change works as intended and also document
+concisely what is being changed. Ideally, your new tests fail
+prior to your change, and succeed once it has been applied. You may
+find this simpler to achieve if you write the tests first.
+
+If you're spiking some code that's experimental and not being used to support
+production features, exceptions can be made to requirements for tests.
+Note that tests will still be required in order to ship the feature, and it's
+strongly encouraged to think about tests early in the process, as adding
+tests later will become progressively more difficult.
+
+If you're not sure how to approach writing tests for your change, ask for help
+in [#element-dev](https://matrix.to/#/#element-dev:matrix.org).

+==============

+The preferred method for merging pull requests is squash merging to keep the

+handle them. When merging make sure to leave the default commit title, or 
+at least leave the PR number at the end in brackets like by default.
+When stacking pull requests, you may wish to do the following:
+
+1. Branch from develop to your branch (branch1), push commits onto it and open a pull request
+2. Branch from your base branch (branch1) to your work branch (branch2), push commits and open a pull request configuring the base to be branch1, saying in the description that it is based on your other PR.
+3. Merge the first PR using a merge commit otherwise your stacked PR will need a rebase. Github will automatically adjust the base branch of your other PR to be develop.
