## Running unit tests with coverage enabled
|
|
|
|
Running unit tests with coverage enabled can be done with the following commands, this will generate a `integrationcover.log`
|
|
```bash
|
|
go test -covermode=atomic -coverpkg=./... -coverprofile=integrationcover.log $(go list ./... | grep -v '/cmd/')
|
|
go tool cover -func=integrationcover.log
|
|
```
|
|
|
|
## Running Sytest with coverage enabled
|
|
|
|
To run Sytest with coverage enabled:
|
|
|
|
```bash
|
|
docker run --rm --name sytest -v "/Users/kegan/github/sytest:/sytest" \
|
|
-v "/Users/kegan/github/dendrite:/src" -v "$(pwd)/sytest_logs:/logs" \
|
|
-v "/Users/kegan/go/:/gopath" -e "POSTGRES=1" \
|
|
-e "COVER=1" \
|
|
matrixdotorg/sytest-dendrite:latest
|
|
|
|
# to get a more accurate coverage you may also need to run Sytest using SQLite as the database:
|
|
docker run --rm --name sytest -v "/Users/kegan/github/sytest:/sytest" \
|
|
-v "/Users/kegan/github/dendrite:/src" -v "$(pwd)/sytest_logs:/logs" \
|
|
-v "/Users/kegan/go/:/gopath" \
|
|
-e "COVER=1" \
|
|
matrixdotorg/sytest-dendrite:latest
|
|
```
|
|
|
|
This will generate a folder `covdatafiles` in each server's directory, e.g `server-0/covdatafiles`. To parse them,
|
|
ensure your working directory is under the Dendrite repository then run:
|
|
|
|
```bash
|
|
go tool covdata func -i="$(find -name 'covmeta*' -type f -exec dirname {} \; | uniq | paste -s -d ',' -)"
|
|
```
|
|
which will produce an output like:
|
|
```
|
|
...
|
|
github.com/matrix-org/util/json.go:132: MakeJSONAPI 70.0%
|
|

github.com/matrix-org/util/unique.go:55: UniqueStrings 100.0%
|
|
total (statements) 64.0%
|
|
```
|
|
(after running Sytest for Postgres _and_ SQLite)
|
|
|
|
The total coverage for this run is the last line at the bottom. However, this value is misleading because Dendrite can run in different configurations,
|
|
which will never be tested in a single test run (e.g sqlite or postgres). To get a more accurate value, you'll need run Sytest for Postgres and SQLite (see commands above).
|
|
Additional processing is required also to remove packages which will never be tested and extension MSCs:
|
|
|
|
```bash
|
|
# If you executed both commands from above, you can get the total coverage using the following commands
|
|
go tool covdata textfmt -i="$(find -name 'covmeta*' -type f -exec dirname {} \; | uniq | paste -s -d ',' -)" -o sytest.cov
|
|
grep -Ev 'relayapi|setup/mscs' sytest.cov > final.cov
|
|
go tool cover -func=final.cov
|
|
|
|
# If you only executed the one for Postgres:
|
|
go tool covdata textfmt -i="$(find -name 'covmeta*' -type f -exec dirname {} \; | uniq | paste -s -d ',' -)" -o sytest.cov
|
|
grep -Ev 'relayapi|sqlite|setup/mscs' sytest.cov > final.cov
|
|
go tool cover -func=final.cov
|
|
|
|
# If you only executed the one for SQLite:
|
|
go tool covdata textfmt -i="$(find -name 'covmeta*' -type f -exec dirname {} \; | uniq | paste -s -d ',' -)" -o sytest.cov
|
|
grep -Ev 'relayapi|postgres|setup/mscs' sytest.cov > final.cov
|
|
go tool cover -func=final.cov
|
|
```
|
|
|
|
## Getting coverage from Complement
|
|
|
|
Getting the coverage for Complement runs is a bit more involved.
|
|
|
|
First you'll need a docker image compatible with Complement, one can be built using
|
|
```bash
|
|
docker build -t complement-dendrite -f build/scripts/Complement.Dockerfile .
|
|
```
|
|
from within the Dendrite repository.
|
|
|
|
Clone complement to a directory of your liking:
|
|
```bash
|
|
git clone https://github.com/matrix-org/complement.git
|
|
cd complement
|
|
```
|
|
|
|
Next we'll need a script to execute after a test finishes, create a new file `posttest.sh`, make the file executable (`chmod +x posttest.sh`)
|
|
and add the following content:
|
|
```bash
|
|
#!/bin/bash
|
|
|
|
mkdir -p /tmp/Complement/logs/$2/$1/
|
|
docker cp $1:/tmp/covdatafiles/. /tmp/Complement/logs/$2/$1/
|
|
```
|
|
This will copy the `covdatafiles` files from each container to something like
|
|
`/tmp/Complement/logs/TestLogin/94f9c428de95779d2b62a3ccd8eab9d5ddcf65cc259a40ece06bdc61687ffed3/`. (`$1` is the containerID, `$2` the test name)
|
|
|
|
Now that we have set up everything we need, we can finally execute Complement:
|
|
```bash
|
|
COMPLEMENT_BASE_IMAGE=complement-dendrite \
|
|
COMPLEMENT_SHARE_ENV_PREFIX=COMPLEMENT_DENDRITE_ \
|
|
COMPLEMENT_DENDRITE_COVER=1 \
|
|
COMPLEMENT_POST_TEST_SCRIPT=$(pwd)/posttest.sh \
|
|
go test -tags dendrite_blacklist ./tests/... -count=1 -v -timeout=30m -failfast=false
|
|
```
|
|
|
|
Once this is done, you can copy the resulting `covdatafiles` files to your Dendrite repository for the next step.
|
|
```bash
|
|
cp -pr /tmp/Complement/logs PathToYourDendriteRepository
|
|
```
|
|
|
|
You can also run the following to get the coverage for Complement runs alone:
|
|
```bash
|
|
go tool covdata func -i="$(find /tmp/Complement -name 'covmeta*' -type f -exec dirname {} \; | uniq | paste -s -d ',' -)"
|
|
```
|
|
|
|
## Combining the results of (almost) all runs
|
|
|
|
Now that we have all our `covdatafiles` files within the Dendrite repository, you can now execute the following command, to get the coverage
|
|
overall (excluding unit tests):
|
|
```bash
|
|
go tool covdata func -i="$(find -name 'covmeta*' -type f -exec dirname {} \; | uniq | paste -s -d ',' -)"
|
|
``` |
