test-clients's Introduction

test-clients

Test utility of HTTP Clients implementations

Build

Pre-Requisites

  • Java 11
  • Maven 3

Build the Jar

mvn clean install

This produces the target/test-clients-1.0-SNAPSHOT-jar-with-dependencies.jar that can be used in any environment with Java to run out tests.

Run

Pre-Requisites

  • Java 11

How to Run

You can run the tool with the following command:

java -cp test-clients-1.0-SNAPSHOT-jar-with-dependencies.jar com.dohbedoh.Main <requestURL>

This will send a request in a loop and print information about requests / response. The default interval between requests is 90 seconds. That give enough time to test changes in the environment (DNS, IP, Firewall, etc...).

Arguments

  • requestURL: the request URL to test against

Environment variables

Following environment variables can be used to pass Basic authentication details to reach out to the test URL, if necessary:

  • TEST_USER: the username
  • TEST_PASS: the password

Note: Both must be set to use Basic authentication.

System Properties

  • com.dohbedoh.requestInterval: Interval between requests in Milliseconds. Default to 90000.
  • com.dohbedoh.proxyHost: An HTTP Proxy host address. Default to null.
  • com.dohbedoh.proxyPort: An HTTP Proxy port. Default to null.
  • com.dohbedoh.recreateClients: Recreate clients between attempts. Default to false, the same client is being used in the loop.

Examples

Request URL

Test a request against a simple URL:

java -cp test-clients-1.0-SNAPSHOT-jar-with-dependencies.jar com.dohbedoh.Main "https://api.github.com/rate_limit/"

With Docker:

docker run -ti --rm dohbedoh:test-clients:1.0 "https://api.github.com/rate_limit/"
