 ## Evaluating pull requests
 
-Oftentimes all you want to do is see if a given pull request solves the issue you were having. To make this easier, the Travis CI setup for snapcraft _publishes_ the resulting snap that was built for x86-64 using `transfer.sh`.
-To download the snap, find the relevant CI job run for the PR under review and locate the "snap" stage, the URL to download from will be located at the end of logs for that job.
+Oftentimes all you want to do is see if a given pull request solves the issue you were having. To make this easier, a snap is published for `amd64` on a channel named `latest/edge/pr-<PR number>` where `PR number` is the number of the pull request.
+
+For feature branches, a snap is published for `amd64` on a channel named `latest/edge/<branch name>`. For example, a branch named `feature/offline-mode` would be available on the channel `latest/edge/offline-mode`.

 At any time, an integration test may fail and given the use of temporary directories it can be hard to inspect what went on. When working on a specific test case you can set the environment variable `SNAPCRAFT_TEST_KEEP_DATA_PATH` to a directory path for the sepecic test.
 This mechanism will only work when working with individual tests and will fail to run with a batch of them.
 
-### Slow tests
-
-Some tests take too long. This affects the pull requests because we have to wait for a long time, and they will make Travis CI timeout because we have only 50 minutes per suite in there. The solution is to tag these tests as slow, and don't run them in all pull requests. These tests will only be run in autopkgtests.
-
-To mark a test case as slow, set the class attribute `slow_test = True`.
-
-To run all the tests, including the slow ones, set the environment variable `SNAPCRAFT_SLOW_TESTS=1`.

 ### Snaps tests
 
 The snaps tests is a suite of high-level tests that try to simulate real-world scenarios of a user interacting with snapcraft. They cover the call to snapcraft to generate a snap file from the source files of a fully functional project, the installation of the resulting snap, and the execution of the binaries and services of this snap.

-## Autopkgtests for the snapcraft deb
-
-Autopkgtests are tests for the project packaged as a deb. The unit tests are run during autopkgtests while the snapcraft deb is being built. Then the resulting deb is installed, and the integration and snaps suites are executed using the installed snapcraft.

-### How to run on Xenial
-
-The easiest way is to use a LXC container. From the root of the project, run:
-
-    sudo apt install autopkgtest
-    adt-run --unbuilt-tree . --apt-upgrade --- lxd ubuntu:xenial
-
-It's possible to select only one of the suites using `--testname`, for example:
-
-    adt-run --unbuilt-tree . --apt-upgrade --testname=integrationtests --- lxd ubuntu:xenial

-The easiest way is to use a LXC container. From the root of the project, run:

 ## Spread tests for the snapcraft snap
 
 [Spread](https://github.com/canonical/spread) is a system to distribute tests and execute them in different backends, in parallel. We are currently using spread only to run the integration suite using the installed snapcraft snap from the edge channel.
