Apache JMeter vs Sauce Labs comparison

Apache JMeter is an open-source Java application that tests load and functional behavior and performance in applications. Created initially to test web applications, it has expanded its functionality to test other functions. For instance, you can test a server to see how efficiently it works and how many user requests can be handled simultaneously.

You can use JMeter to test functional performance and regression tests on different technologies. This Java desktop application has an easy-to-use graphical interface which uses the Swing graphical API. You can run JMeter on any environment that accepts a Java virtual machine, such as Windows, Linux, and Mac.

What protocols does JMeter support?

• Web - HTTP, HTTPS
• Web services - SOAP/XML-RPC
• Email service - POP3, IMAP, SMTP
• FTP service
• Database via JDBC drivers
• LDAP
• Native commands or shell scripts
• TCP
• Java objects

How does JMeter work?

JMeter sends requests to a target server by simulating a group of user requests. Then it collects and calculates statistics on the performance of the target. This target can be a server or an application.

You can test the performance of static resources, such as JavaScript or HTML, and dynamic resources, such as JSP, Servlets, and AJAX. It is also helpful to determine how many concurrent users your website can handle.

There are two main tests you can carry out with JMeter: load test and stress test. The load test models expected usage of a server by simulating multiple users accessing the web server simultaneously. The stress testing aims to find the maximum load capacity of the server or application.

Apache JMeter Key Features

• JMeter enables fast test plan recording, building, and debugging via a featured test IDE (integrated development environment).
• Command-line mode allows carrying out load tests from any OS compatible with Java.
• JMeter can extract data from most popular response formats, such as HTML, JSON, XML.
• JMeter is entirely portable.
• A multithreading framework allows you to simultaneously test multiple samplings and separate thread groups.
• Thanks to the caching feature, you can conduct offline analysis or replay test results.

Apache JMeter Benefits

• As open-source software, it is freely available and continuously improved.
• The setup is user-friendly, and no installation is needed.
• The GUI (graphic user interface) is intuitive and easy to use.
• You can write your own tests and use the visualization plugins to extend the testing.
• It is a platform-agnostic tool. For example, JMeter can work with Linux by clicking on the JMeter shell script. On Windows, you can call up JMeter by starting the jmeter.bat file.
• Since the test plans are stored in XML format, you can generate a test plan using any text editor.
• You can simulate a heavy load on a server, a group of servers, a network, or an object. Use JMeter to test an application or server's strength and performance under different load types.

The JMeter extensible core has numerous benefits:

• Unlimited testing capabilities via pluggable samplers.
• You can choose multiple load statistics with pluggable timers.
• Visualization plugins and data analysis enable customization.
• Continuous integration via third-party open-source libraries (Maven, Gradle, and Jenkins).

Reviews from Real Users

Stephen B., I.T. Architect, Analyst, and Developer at an educational organization, says, "The scripting ability is most valuable. It is easy to use. There is a UI, and you can go in there and figure those things out. After you've got a good set of tests, you basically have a scripted document that you can grab and execute in a pipeline. It is pretty quick to set up, and you can scale it and version control it."

"I like the fact that JMeter integrates well with other tools," adds the Founder and Principal Consultant at a tech services company.

A Quality Engineering Delivery Leader at a financial services firm says, “The performance of the solution is excellent. They have designed the product so that it is very easy to configure. You can basically do anything you like with the product. It's not very restrictive. We like the fact that the technology is open-source.”

Sauce Labs is a functional testing tool that ensures your apps and websites work flawlessly on every browser, OS, and device. The solution allows you to automate functional testing on multiple operating systems and browsers, emulating the way that a user would use the website. With Sauce Labs, you can also run tests on various operating system and browser combinations in parallel, reducing the amount of time to get results. The Sauce Labs solution provides enterprise-grade security, scalability, and reliability.

Sauce Labs Features

Sauce Labs has many valuable key features. Some of the most useful ones include:

• Automated cross-browser testing
• Mobile testing
• Secure tunneling protocol
• Usage reporting
• Enterprise security
• Provisioning
• Centralized user account management
• Access controls
• Support for Selenium, Appium, and JUnit Testing

Sauce Labs Benefits

There are many benefits to implementing Sauce Labs. Some of the biggest advantages the solution offers include:

• Speed up development time: The solution makes it possible for you to test web and mobile apps in parallel and accelerate your testing time by up to 10x or more. Using Sauce Labs, you can increase developer productivity because your teams will be able to spend less time with test maintenance and debug faster.

• No worrying about infrastructure: With Sauce Labs, you don’t have to buy or maintain more servers or mobile devices. You also don’t need to worry about updating browsers or VM licenses. Sauce Labs allows you to easily scale your tests with parallelization to speed up test cycles and boost capacity on their reliable cloud.

• Run tests securely: The solution enables you to securely run your scripts and access your data and files from behind your firewall. Sauce Labs generates single-use VMs for every test and destroys them immediately afterwards so your data always remains secure.

• Easy integration for your CI systems: Sauce Labs automated testing platform integrates with Jenkins, Bamboo, Microsoft VSTS, and others so you can test as fast as you develop. In addition, you can share results instantly by using the solution’s simple plugins.

Reviews from Real Users

Sauce Labs is a solution that stands out when compared to many of its competitors. It has valuable features that include error logging, helpful dashboards, and its browser.

Joel A., Product Manager - Data & APIs at a marketing services firm, says, "The error logging is very robust. If we run a test through Sauce Labs and there's some sort of issue, a log will appear on the screen. Log messages are usually heinous and horrible... Sauce Labs is incredibly good at saying things like, 'Hey, here is the exact issue. Fix this and you can run the test.' That helps in getting things up and running and executing the way they should."

Savio D., Sr. IT Architect at a healthcare company, mentions, "Sauce Labs' dashboards contain multiple useful metrics in one place. Everything is represented to us visually on the dashboard, which helps us understand where to focus our attention, what the issues are, and what we need to resolve."

PeerSpot reviewer, Rob L., Director of Quality Assurance - Shared Service at a financial services firm, writes, “The most valuable feature for us is the browser. The most critical thing is that this software aligns with our Agile and DevOps way of doing things. It integrates with kickoff scripts through DevOps.”
