CF Acceptance Tests

This test suite exercises a full Cloud Foundry deployment using the gcf CLI and curl. It is restricted to testing high-level user-facing features that touch more than one component in the deployment.

For example, one test pushes an app with gcf push, hits an endpoint on the app with curl that causes it to crash, and asserts that we eventually see a crash event registered in gcf events.

Tests that will NOT be introduced here are things that only really test one single component, like basic CRUD of an object in the CC. These tests belong further down.

When running the tests, they will use gcf in whatever state it's already configured for. Setting up users and organizations and spaces is out of scope. This simplifies the tests themselves and is likely more natural for someone testing their own CF deployment, as they're probably kicking the tires on it themselves.

Running the tests

You will need a working Go environment with $GOPATH set, and you will need gcf and curl in your $PATH.

See Go CLI for instructions on installing gcf. See Go for instructions on installing go.

Configuration

Before running the tests, you must make sure you've logged in to your runtime environment and targeted a space using

  gcf target -o [your_org] -s [your_space]

You must also set $CONFIG to point to a .json file which contains the configuration for the tests.

There is not much to configure - for now you just need to set the domain that the deployment is configured to use for the apps, and set several environment variables.

The tests must run as a user - you must create a user and specify its credentials in the env vars.

For example, to run these against a local BOSH lite deployment, you'll likely need:

cat > integration_config.json <<EOF
{ "apps_domain": "10.244.0.34.xip.io" }
EOF

export ADMIN=admin-username
export ADMIN_PASSWORD=admin-password
export CF_USER=cf-user-username
export CF_USER_PASSWORD=cf-user-password
export CF_ORG=org-name
export CF_SPACE=space-name
export API_ENDPOINT=http://cf.api.endpoint.url.com

Running

To run the CF Acceptance tests, you need to be logged in and targeting an empty space and org (we suggest the cats-space inside the cats-org).

gcf logout
gcf api api.10.244.0.34.xip.io
gcf auth admin admin
gcf create-org cats-org
gcf target -o cats-org
gcf create-space cats-space
gcf target -o cats-org -s cats-space
export CONFIG=$PWD/integration_config.json
./bin/test [ginkgo arguments ...]

The test script will pass any given arguments to ginkgo, so this is where you pass -focus=, -nodes=, etc.

Running in parallel

To run the tests in parallel, pass -nodes=X, where X is how many examples to run at once.

./bin/test -nodes=10

Be careful with this number, as it's effectively "how many apps to push at once", as every example probably pushes an app. For a BOSH Lite deployment, you may want to just set this to 10. For a larger AWS deployment, 100 may be just fine.

Seeing command-line output

If you want to see the output of all of the commands it shells out to, set CF_VERBOSE_OUTPUT to true.

export CF_VERBOSE_OUTPUT=true
./bin/test

Capturing CF cli output

If CF_TRACE_BASENAME is set, then CF_TRACE will be set to ${CF_TRACE_BASENAME}${Ginko Node Id}.txt for each invocation of gcf.

Example:
export CF_TRACE_BASENAME=cf_trace_
./bin/test -nodes=10

The following files may be created:

cf_trace_1.txt
cf_trace_2.txt
cf_trace_3.txt
cf_trace_4.txt
cf_trace_5.txt
cf_trace_6.txt
cf_trace_7.txt
cf_trace_8.txt
cf_trace_9.txt
cf_trace_10.txt

If a test fails, look for the node id is the test output:

=== RUN TestLifecycle

Running Suite: Application Lifecycle
====================================

Parallel test node 2/10. Assigned 14 of 137 specs.

The gcf trace output for the tests in these specs will be in in cf_trace_2.txt
