Leapwork vs TestComplete – Differences You Must Know

Leapwork and TestComplete are two well-known testing tools that make automation easier. But they are made for different users. 

Leapwork is a no-code tool. It lets testers and business users create tests using a simple flowchart-based system. This makes it good for teams with little coding skills. On the other hand, TestComplete is a robust script-based tool. It supports many programming languages like Python, JavaScript, and VBScript. It gives more control to developers and testers who know coding.

Both tools have their unique strengths but also some limitations. Leapwork is easy to use but may not work well for complex tests that need custom coding. Also, its license costs more than that of some other tools. TestComplete is flexible but harder to learn. It needs programming skills, which can be tough for testers who don’t code.

Because of these issues, many teams look for other options like Testsigma. It gives a mix of low-code and AI-powered automation. It helps both coders and non-coders create test cases using simple English natural language and also scales better.

What is Leapwork?

Leapwork is a no-code tool that makes test automation easier. It helps both coders and non-coders create tests using visual blocks instead of writing scripts. The platform uses a flowchart-style interface where you drag-drop elements to build tests. It supports web apps, desktop software, and API testing. This makes it a flexible choice for teams wanting a faster testing process. Also works well with DevOps tools for CI/CD pipelines.

A big plus point is the visual debugging feature. Testers can check failed tests using video records and screenshots. Leapwork also uses AI to update tests automatically when apps change. This means less work fixing broken tests.

But it has some downsides as well. Cost is high for licenses. Also, it’s hard to customize tests for complex automation needs. Even with these limits, Leapwork stays popular for companies wanting low-code/no-code solutions. It’s good for beginners but maybe not enough for advanced users.

What is TestComplete?

TestComplete is a UI testing tool from SmartBear. It lets teams make and run tests for web apps, desktop software, and mobile apps. Users can choose between scripted and scriptless automation. They can write tests in Python, JavaScript, or VBScript or use the record-and-replay feature for codeless testing.

TestComplete focuses on UI testing. The tool uses AI to find UI elements automatically. It’s particularly helpful when apps change often. It’s also easy to integrate with CI/CD pipelines, making it a good choice for DevOps teams.

One big advantage of TestComplete is cross-platform testing. You can test apps on Windows, macOS, Android, and iOS devices. You can also do data-driven testing – run the same test with different inputs.

But there are some drawbacks. The licensing cost is high, and advanced scripting has a steep learning curve. It may also not scale well for large enterprise automation. Still, TestComplete is a strong choice for teams looking for a UI automation tool with both codeless and scripting options.

What is Testsigma? – Best Alternative to Leapwork and TestComplete

Testsigma is a cloud-based AI-driven test automation platform. It makes automated testing on web, mobile, and API apps simple and easy. Unlike Leapwork and TestComplete which have platform limits and steep learning curves, Testsigma uses a low-code and scriptless way. This makes automation available to both technical and non-technical users. It supports natural language scripting so testers can write tests in simple English. This removes the need for heavy coding.

Testsigma also supports seamless cloud execution. It allows us to run tests in parallel across many environments without needing on-premise hardware. With built-in integrations for CI/CD pipelines, test management, and reporting, it creates a full automation ecosystem for agile teams.

One big advantage of Testsigma over Leapwork and TestComplete is its scalability and cross-platform support. While Leapwork struggles with complex flowcharts and TestComplete is Windows-centric, Testsigma is platform agnostic. 

Moreover, it can run tests on Windows, macOS, Linux, and cloud-based environments. Its AI-driven maintenance helps reduce test flakiness by automatically updating test scripts when UI changes. Testsigma also offers better cost efficiency. It removes high licensing fees and expensive infrastructure costs that come with TestComplete and Leapwork.

What are the Limitations of Leapwork?

Leapwork makes test automation easy with its no-code visual flowcharts. But it has some limits that affect big projects and speed. The visual interface is good for simple tests but gets messy when projects grow big. Also, Leapwork doesn’t let you do much with custom scripts. Teams needing advanced coding might find it too basic. Tests run slower than code-based tools. This is a problem if you have many tests to run. It’s also expensive. Plus, not many users share tips or help online. Startups and small teams might not be able to afford or get enough support.

Key Limitations of Leapwork:

• Flowcharts Get Too Big – When tests get big, the visual charts are hard to fix or manage.
• Can’t Add Custom Code – No way to write your own scripts or handle tricky automation needs.
• Slower Testing – Runs tests slower than tools that use code. Wastes time.
• Costs Too Much – Price is high. Not good for small companies or new startups.
• Small User Community – Not many people use Leapwork like Selenium. Fewer guides or updates from others.
• Some Tools Don’t Work – Works with CI/CD tools but not all other testing systems.
• Hard to Learn for Big Tests – Even with no code, big projects need expert skills.

Leapwork is still good if you want easy no-code testing. But for bigger needs, try tools like Testsigma for better speed and options.

What Does TestComplete Offer?

TestComplete is a full-featured UI testing tool for web, desktop, and mobile apps. It lets you create tests in two ways: by writing code (Python, JavaScript, VBScript) or using record-and-replay without coding. It is great for both experts and beginners. The tool uses AI to find UI elements even if they change often. This makes tests more stable. It works smoothly with CI/CD pipelines, DevOps tools, and cloud testing setups so you can run tests non-stop. You can also test apps with different data inputs from Excel, CSV, or databases to cover many scenarios. For fixing issues, TestComplete gives videos, screenshots, and logs to see why tests failed.

Key Features of TestComplete:

• Code or No-Code Tests – Use record-and-replay for simple tests or code for complex ones.
• AI Finds UI Elements – Even if app UI changes, AI keeps tests working.
• Test Any Device – Works on Windows, macOS, Android, and iOS apps.
• Run Tests Faster – Run the same test on multiple devices at once.
• Test With Real Data – Pull data from databases, Excel, and CSV files for realistic testing.
• Works With DevOps Tools – Connects to Jenkins, Azure DevOps, GitHub, etc. for CI/CD.
• Test Anywhere – Run tests on your servers or in a cloud-like BrowserStack.
• Easy Debugging – Use logs, screenshots, and videos to find errors quickly.

TestComplete is a strong choice for teams wanting flexible, AI-powered testing that works with DevOps. It supports coding and no-code methods so everyone can use it.

What are the Limitations of TestComplete?

TestComplete is a robust tool for UI testing but has some problems. It mainly works well for Windows apps but not so much for macOS and Linux. Even though it allows scripted and no-code tests, the record-and-replay feature sometimes makes easily breakable scripts. You need to fix them manually. Also, it costs a lot of money which small companies or startups can’t afford. Tests run slow too, especially when the UI is complex. Learning to use TestComplete is hard for new people. Plus, not much help from online communities like open-source tools have.

Key Limitations of TestComplete:

• Mostly Only Windows – Works best for Windows apps. Not good for Mac or Linux systems.
• Scripts Break Often – Record-and-replay makes scripts that need manual fixing.
• Too Expensive – The price is high which is bad for small teams or solo testers.
• Slow Test Runs – Slower than tools like Selenium when testing complex UIs.
• Hard to Learn – Need to know a lot about UI elements and how tools work.
• Few Help Online – Not a big community like Selenium. Fewer guides or fixes from others.
• Cloud Setup Tricky – Works with CI/CD tools but is hard to connect with other cloud testing systems.

TestComplete is still ok if you test Windows apps mostly. But for a better price, speed, and cross-platform, tools like Testsigma are better choices.
