# Quidem UT
|
|
|
|
Enables to write sql level tests easily.
|
|
Can be used to write tests against existing test backends (ComponentSupplier) - by doing so the testcases can be moved closer to the exercised codes.
|
|
|
|
## Usage
|
|
|
|
### Install java&maven (if needed)
|
|
|
|
If you don't have java&maven - one way to set that up is by using sdkman like this:
|
|
```bash
|
|
# install sdkman
|
|
curl -s "https://get.sdkman.io" | bash
|
|
# at the end of installation either open a new terminal; or follow the instructions at the end
|
|
|
|
# install java&maven
|
|
sdk install java 11.0.23-zulu
|
|
sdk install maven
|
|
|
|
# run mvn to see if it works
|
|
mvn --version
|
|
|
|
# download druid sources
|
|
git clone https://github.com/apache/druid
|
|
```
|
|
|
|
|
|
|
|
|
|
### Running these tests
|
|
|
|
* CI execution happens by a standard JUnit test `QTest` in this module
|
|
* the `dev/quidem` script can be used to run these tests (after the project is built)
|
|
|
|
### Launching a test generating broker
|
|
|
|
* make sure to build the project first; one way to do that is:
|
|
```bash
|
|
mvn install -pl quidem-ut/ -am -DskipTests -Pskip-static-checks
|
|
```
|
|
* launch the broker instance with:
|
|
```bash
|
|
mvn exec:exec -pl quidem-ut -Dquidem.record.autostart=true
|
|
```
|
|
* the broker will be running at http://localhost:12345
|
|
* the used test configuration backend can configured by supplying `quidem.uri`
|
|
```bash
|
|
mvn exec:exec -pl quidem-ut -Dquidem.uri=druidtest:///?componentSupplier=ThetaSketchComponentSupplier
|
|
```
|
|
* new record files can be started by calling http://localhost:12345/quidem/start
|
|
* if `quidem.record.autostart` is omitted recording will not start
|
|
* after finished with the usage of the broker ; a new `record-123.iq` file will be in the project's worktree - it will contain all the executed statements
|
|
* running `dev/quidem -Dquidem.overwrite` updates the resultsets of all `iq` files around there
|
|
* rename the testfile to have a more descriptive name
