+# App Integration Tests
+
+The `apptest` package contains the integration tests for the VictoriaMetrics
+applications (such as vmstorage, vminsert, and vmselect).
+
+An integration test aims at verifying the behavior of an application as a whole,
+as apposed to a unit test that verifies the behavior of a building block of an
+application.
+
+To achieve that an integration test starts an application in a separate process
+and then issues HTTP requets to it and verifies the responses, examines the
+metrics the app exposes and/or files it creates, etc.
+
+Note that an object of testing may be not just a single app, but several apps
+working together. A good example is VictoriaMetrics cluster. An integration test
+may reproduce an arbitrary cluster configuration and verify how the components
+work together as a system.
+
+The package provides a collection of helpers to start applications and make
+queries to them:
+
+-   `app.go` - contains the generic code for staring an application and should
+    not be used by integration tests directly.
+-   `{vmstorage,vminsert,etc}.go` - build on top of `app.go` and provide the
+    code for staring a specific application.
+-   `client.go` - provides helper functions for sending HTTP requests to
+    applications.
+
+The integration tests themselves reside in `*_test.go` files. Apart from having
+the `_test` suffix, there are no strict rules of how to name a file, but the
+name should reflect the prevailing purpose of the tests located in that file.
+For example, `sharding_test.go` aims at testing data sharding.
+
+Since integration tests start applications in a separate process, they require
+the application binary files to be built and put into the `bin` directory. The
+build rule used for running integration tests, `make integration-test`,
+accounts for that, it builds all application binaries before running the tests.
+But if you want to run the tests without `make`, i.e. by executing
+`go test ./app/apptest`, you will need to build the binaries first (for example,
+by executing `make all`).

+# Docker compose Journald integration with VictoriaLogs
+
+The folder contains examples of Journald integration with VictoriaLogs using protocols:
+
+* [journald](./journald)
+
+To spin-up environment `cd` to any of listed above directories run the following command:
+```
+docker compose up -d 
+```
+
+To shut down the docker-compose environment run the following command:
+```
+docker compose down
+docker compose rm -f
+```
+
+The docker compose file contains the following components:
+
+* journald - Journald logs collection agent, which is configured to collect and write data to `victorialogs`
+* victorialogs - VictoriaLogs log database, which accepts the data from `journald`
+* victoriametrics - VictoriaMetrics metrics database, which collects metrics from `victorialogs` and `journald`
+
+Querying the data
+
+* [vmui](https://docs.victoriametrics.com/victorialogs/querying/#vmui) - a web UI is accessible by `http://localhost:9428/select/vmui`
+* for querying the data via command-line please check [these docs](https://docs.victoriametrics.com/victorialogs/querying/#command-line)
+
+Please, note that `_stream_fields` parameter must follow recommended [best practices](https://docs.victoriametrics.com/victorialogs/keyconcepts/#stream-fields) to achieve better performance.
