Keploy with PetClinic

This is a petclinic app where you can record testcases and mocks by interacting with the UI, and then test them using Keploy.

🛠️ Platform-Specific Requirements for Keploy

Below is a table summarizing the tools needed for both native and Docker installations of Keploy on MacOS, Windows, and Linux:

Operating SystemWithout DockerDocker InstallationPrerequisites
MacOS MacOSNot SupportedSupportedDocker Desktop version must be 4.25.2 or above
Windows WindowsSupportedSupported- Use WSL wsl --install
- Windows 10 version 2004 and higher (Build 19041 and higher) or Windows 11
Linux LinuxSupportedSupportedLinux kernel 5.15 or higher

On MacOS and Windows, additional tools are required for Keploy due to the lack of native eBPF support.

Quick Installation

Let's get started by setting up the Keploy alias with this command:

 curl -O && source

Keploy CLI

Available Commands:
example Example to record and test via keploy
generate-config generate the keploy configuration file
record record the keploy testcases from the API calls
test run the recorded testcases and execute assertions
update Update Keploy

--debug Run in debug mode

Use "keploy [command] --help" for more information about a command.

🎉 Wohoo! You are all set to use Keploy.

This project has two parts - the frontend and backend, since Keploy is a backend testing platform, we need to start the backend part of the project using Keploy and run the frontend as it is.

Setup the frontend

git clone
cd samples-java/spring-petclinic/spring-petclinic-angular
npm uninstall -g angular-cli @angular/cli
npm cache clean
npm install -g @angular/cli@latest
npm install --save-dev @angular/cli@latest
npm i

Start the frontend

npm run start

Now it's time to setup the backend of our application. Let's move to the backend directory and get started.

cd samples-java/spring-petclinic/spring-petclinic-rest

You can start the backend using Keploy in 2 ways:

Instructions For Starting Using Binary

Prerequisites For Binary:

  1. Node 20.11.0 LTS
  2. OpenJDK 17.0.9
  3. MVN version 3.6.3

Setup the backend

You need to update the postgresql properties, go to spring-petclinic/spring-petclinic-rest/src/main/resources/ and change




and then build the jar using:

mvn clean install -Dmaven.test.skip=true

Spin up the database

docker run -e POSTGRES_USER=petclinic -e POSTGRES_PASSWORD=petclinic -e POSTGRES_DB=petclinic -p 5432:5432 --name mypostgres postgres:15.2

Recording the testcases with Keploy

keploy record -c "java -jar target/spring-petclinic-rest-3.0.2.jar"

Now you can start interacting with the UI and Keploy will automatically create the testcases and mocks for it in a folder named 'keploy'.

Running the testcases using Keploy

keploy test -c "java -jar target/spring-petclinic-rest-3.0.2.jar" --delay 20

🎉 Hooray! You've made it to the end of the binary section! 🎉

Next we move on to the instructions to start the application using docker.

Instructions For Starting Using Docker

Prerequisites For Docker:

  1. Docker Desktop 4.25.2 and above

Here we just need to change the command used to start the application.

keploy record -c "docker compose up" --containerName javaApp --buildDelay 100s

Running the testcases using Keploy

keploy test -c "docker compose up" --containerName javaApp --buildDelay 50s --delay 20

Here delay is the time it takes for your application to get started, after which Keploy will start running the testcases. If your application takes longer than 10s to get started, you can change the delay accordingly. buildDelay is the time that it takes for the image to get built. This is useful when you are building the docker image from your docker compose file itself.
