Apache JMeter vs Postman: What are the differences?

Introduction

In this article, we will explore the key differences between Apache JMeter and Postman, two popular tools used for API testing and performance measurement. These tools offer various features and functionalities that cater to different needs and requirements in the software testing field.

  1. Test Execution Environment: One significant difference between Apache JMeter and Postman lies in their test execution environment. Apache JMeter is a Java-based open-source tool that runs on the Java Virtual Machine (JVM). It allows users to design and execute performance tests across different protocols like HTTP, HTTPS, FTP, JDBC, and more. On the other hand, Postman is a lightweight tool that runs natively on desktop operating systems (Windows, macOS, and Linux) as a standalone application. It primarily focuses on RESTful API testing and provides a user-friendly interface to create and execute API tests.

  2. Test Scripting: When it comes to test scripting, Apache JMeter uses a GUI-based Test Plan approach, where users can design test scenarios by adding various test elements and configuring settings through the graphical interface. It also supports scripting through BeanShell, JSR223, and Groovy for advanced scenarios. In contrast, Postman follows a script-driven approach using JavaScript. Users can write custom scripts directly within the application to manipulate request/response data, perform data validations, and apply logic conditions.

  3. Test Collaboration and Documentation: Apache JMeter provides limited support for collaboration and documentation. It does not offer built-in features for team collaboration, making it challenging for multiple testers to work together on a single test plan. Additionally, generating comprehensive test documentation requires manual effort. In comparison, Postman excels in collaboration and documentation capabilities. It provides a team workspace where testers can easily share collections, collaborate on tests, and track changes made by team members. Postman also provides automated generation of detailed API documentation with rich-text formatting options.

  4. Test Environment Management: Apache JMeter mainly focuses on performance testing and provides extensive features to create and manage test environments. It allows testers to simulate hundreds or thousands of virtual users to mimic real-world scenarios. It also provides server monitoring plugins to track system resource utilization during test execution. In contrast, Postman focuses more on functional and integration testing rather than performance testing. It lacks advanced performance testing features like load generation and monitoring.

  5. Integration with Development Lifecycle: Apache JMeter integrates well with the software development lifecycle. It can be easily integrated with Continuous Integration (CI) tools like Jenkins and build automation tools. This integration enables the inclusion of performance tests in the CI/CD pipeline for early bottleneck detection. Postman, although not primarily designed for integration testing, offers several integrations with CI/CD tools like GitHub, Azure DevOps, and Postman's own monitoring solution, allowing testers to automate API tests within the development workflow.

  6. Customization and Extensibility: Apache JMeter provides extensive customization and extensibility options. Users can create custom plugins and extend JMeter's functionality using Java programming. This flexibility allows testers to tailor the tool to meet their specific requirements. In contrast, Postman's customization options are comparatively limited. While it provides the ability to write custom scripts, the tool's core functionality cannot be extended beyond its existing features and offerings.

In summary, Apache JMeter is a robust and feature-rich tool primarily focused on performance testing with a strong emphasis on scalability and test environment management. On the other hand, Postman is a lightweight yet powerful tool focused on RESTful API testing with excellent collaboration capabilities. Choosing between them depends on the specific testing requirements and priorities of individual projects.

I have a team that is not heavy on programming skills. I am looking for a load testing tool that is easy to use. Preferably, the tool should be a record and playback tool without much programming. Also, the tool should be able to test APIs apart from web-based applications. What tool should I opt for?

My choice would be Apache JMeter, It's free and opensource plus it comes with lots of plugins and extendability. Apache JMeter needs a small amount of a learning curve and a basic understanding of Network, Protocols (TCP/IP ports, HTTP(S) and REST/SOAP, etc.) for initial setup. But it doesn't require programming skills. it has a nice record and playback option. You can still carry on without the developer skillset if you follow these steps. 1. Take backup. 2. Start recording and interact with the application. 3. stop recording and save the test case. This will give you your test-bed, after this, after these steps, every time just do Restore from backup and then Playback and observer results.

If you have longer recordings then an understanding of how to modify the recorded scripts will come handy.

For some of the advanced features such as Configuring variables, implementing loops, throttling adding think time, and automating test scaling to the number of users will require good planning of test scenarios and a Developer experience but this is true for any tool (even loader.io)

Disclaimer: I work at k6, and I recommend you try our tool.

It might require some coding skills, but we support a few options to record a user session to autogenerate the load test. Read How to record a browser session with k6 OSS.

The k6 Cloud also supports recording a user session with a Browser Extension. Additionally, it provides a Test Builder UI to generate a load test for testing APIs.

If you have questions or need help, you can ask on Slack and the Community forum.

From a StackShare Community member: "I just started working for a start-up and we are in desperate need of better documentation for our API. Currently our API docs is in a README.md file. We are evaluating Postman and Swagger UI. Since there are many options and I was wondering what other StackSharers would recommend?"

I use Postman because of the ease of team-management, using workspaces and teams, runner, collections, environment variables, test-scripts (post execution), variable management (pre and post execution), folders (inside collections, for better management of APIs), newman, easy-ci-integration (and probably a few more things that I am not able to recall right now).

I use Swagger UI because it's an easy tool for end-consumers to visualize and test our APIs. It focuses on that ! And it's directly embedded and delivered with the APIs. Postman's built-in tools aren't bad, but their main focus isn't the documentation and also, they are hosted outside the project.

Decisions about Apache JMeter and Postman

Postman supports automation and organization in a way that Insomnia just doesn't. Admittedly, Insomnia makes it slightly easy to query the data that you get back (in a very MongoDB-esque query language) but Postman sets you up to develop the code that you would use in development/testing right in the editor.
