## ClickHouse Tests in [TestFlows]
|
|
|
|
This directory contains integration tests written using [TestFlows]
|
|
that involves several ClickHouse instances, custom configs, ZooKeeper, etc.
|
|
|
|
## Supported environment
|
|
|
|
* [Ubuntu] 18.04
|
|
* [Python 3] >= 3.6
|
|
|
|
## Prerequisites
|
|
|
|
* [Docker] [install](https://docs.docker.com/compose/install/)
|
|
* [Docker Compose] [install](https://docs.docker.com/engine/install/)
|
|
* [TestFlows] [install](https://testflows.com/handbook/#Installation)
|
|
|
|
## Running tests locally
|
|
|
|
You can run tests locally by passing `--local` and `--clickhouse-binary-path` to the `regression.py`.
|
|
|
|
* `--local` specifies that regression will be run locally
|
|
* `--clickhouse-binary-path` specifies the path to the ClickHouse binary that will be used during the regression run
|
|
|
|
> Note: you can pass `-h` or `--help` argument to the `regression.py` to see a help message.
|
|
>
|
|
> ```bash
|
|
> python3 regression.py -h
|
|
> ```
|
|
|
|
> Note: make sure that the ClickHouse binary has correct permissions.
|
|
> If you are using `/usr/bin/clickhouse` its owner and group is set to `root:root` by default
|
|
> and it needs to be changed to `clickhouse:clickhouse`. You can change the owner and the group
|
|
> using the following command.
|
|
>
|
|
> ```bash
|
|
> sudo chown clickhouse:clickhouse /usr/bin/clickhouse
|
|
> ```
|
|
|
|
Using the default ClickHouse installation and its server binary at `/usr/bin/clickhouse`, you can run
|
|
regressions locally using the following command.
|
|
|
|
```bash
|
|
python3 regression.py --local --clickhouse-binary-path "/usr/bin/clickhouse"
|
|
```
|
|
|
|
## Output Verbosity
|
|
|
|
You can control verbosity of the output by specifying the output format with `-o` or `--output` option.
|
|
See `--help` for more details.
|
|
|
|
## Running Only Selected Tests
|
|
|
|
You can run only the selected tests by passing `--only` option to the `regression.py`.
|
|
|
|
For example,
|
|
|
|
```bash
|
|
./regression.py --local --clickhouse-binary-path /usr/bin/clickhouse --only "/clickhouse/rbac/syntax/grant privilege/*"
|
|
```
|
|
|
|
will execute all `rbac/syntax/grant privilege` tests.
|
|
|
|
If you want to run only a single test such as the `/clickhouse/rbac/syntax/grant privilege/grant privileges/privilege='KILL QUERY', on=('*.*',), allow_introspection=False` you can do it as follows
|
|
|
|
```bash
|
|
./regression.py --local --clickhouse-binary-path /usr/bin/clickhouse --only "/clickhouse/rbac/syntax/grant privilege/grant privileges/privilege='KILL QUERY', on=('[*].[*]',), allow_introspection=False/*"
|
|
```
|
|
|
|
> Note that you need to surround special characters such as `*` with square brackets, for example `[*]`.
|
|
|
|
> Note that you need to end the filtering pattern with `/*` to run all the steps inside the test.
|
|
|
|
For more information, please see [Filtering](https://testflows.com/handbook/#Filtering) section in the [TestFlows Handbook].
|
|
|
|
## How To Debug Why Test Failed
|
|
|
|
### Step 1: find which tests failed
|
|
|
|
If [TestFlows] check does not pass you should look at the end of the `test_run.txt.out.log` to find the list
|
|
of failing tests. For example,
|
|
|
|
```bash
|
|
clickhouse_testflows_tests_volume
|
|
Start tests
|
|
➤ Dec 02,2020 22:22:24 /clickhouse
|
|
...
|
|
Failing
|
|
|
|
✘ [ Fail ] /clickhouse/rbac/syntax/grant privilege/grant privileges/privilege='SELECT', on=('db0.table0', 'db0.*', '*.*', 'tb0', '*'), allow_column=True, allow_introspection=False
|
|
✘ [ Fail ] /clickhouse/rbac/syntax/grant privilege/grant privileges
|
|
✘ [ Fail ] /clickhouse/rbac/syntax/grant privilege
|
|
✘ [ Fail ] /clickhouse/rbac/syntax
|
|
✘ [ Fail ] /clickhouse/rbac
|
|
✘ [ Fail ] /clickhouse
|
|
```
|
|
|
|
In this case the failing test is
|
|
|
|
```
|
|
/clickhouse/rbac/syntax/grant privilege/grant privileges/privilege='SELECT', on=('db0.table0', 'db0.*', '*.*', 'tb0', '*'), allow_column=True, allow_introspection=False
|
|
```
|
|
|
|
while the others
|
|
|
|
```
|
|
✘ [ Fail ] /clickhouse/rbac/syntax/grant privilege/grant privileges
|
|
✘ [ Fail ] /clickhouse/rbac/syntax/grant privilege
|
|
✘ [ Fail ] /clickhouse/rbac/syntax
|
|
✘ [ Fail ] /clickhouse/rbac
|
|
✘ [ Fail ] /clickhouse
|
|
```
|
|
|
|
failed because the first fail gets "bubble-up" the test execution tree all the way to the top level test which is the
|
|
`/clickhouse`.
|
|
|
|
### Step 2: download `test.log` that contains all raw messages
|
|
|
|
You need to download the `test.log` that contains all raw messages.
|
|
|
|
### Step 3: get messages for the failing test
|
|
|
|
Once you know the name of the failing test and you have the `test.log` that contains all the raw messages
|
|
for all the tests, you can use `tfs show test messages` command.
|
|
|
|
> You get the `tfs` command by installing [TestFlows].
|
|
|
|
For example,
|
|
|
|
```bash
|
|
cat test.log | tfs show test messages "/clickhouse/rbac/syntax/grant privilege/grant privileges/privilege='SELECT', on=\('db0.table0', 'db0.\*', '\*.\*', 'tb0', '\*'\), allow_column=True, allow_introspection=False"
|
|
```
|
|
|
|
> Note: that characters that are treated as special in extended regular expressions need to be escaped. In this case
|
|
> we have to escape the `*`, `(`, and the `)` characters in the test name.
|
|
|
|
### Step 4: working with the `test.log`
|
|
|
|
You can use the `test.log` with many of the commands provided by the
|
|
`tfs` utility.
|
|
|
|
> See `tfs --help` for more information.
|
|
|
|
For example, you can get a list of failing tests from the `test.log` using the
|
|
`tfs show fails` command as follows
|
|
|
|
```bash
|
|
$ cat test.log | tfs show fails
|
|
```
|
|
|
|
or get the results using the `tfs show results` command as follows
|
|
|
|
```bash
|
|
$ cat test.log | tfs show results
|
|
```
|
|
|
|
or you can transform the log to see only the new fails using the
|
|
`tfs transform fail --new` command as follows
|
|
|
|
```bash
|
|
$ cat test.log | tfs transform fails --new
|
|
```
