Applications of ZAPTEST for Performance Testing Automation

ZAPTEST’s free full-stack tool is used for performance automated testing in many fields, including contact centers, human resources, claims processing, finance and accounting, IT, legal, and healthcare.


Cross-Platform execution is one of the main advantages of ZAPTEST. With a single ZAPTEST Module it’s easy to execute the script on any platform. ZAPTEST completely supports the following platforms: Windows, MacOS, Linux, Android, iOS, and others


Agile isn’t just a software test automation tool. Agile is a methodology. Through the promotion of adaptive planning throughout a software development process and ZAPTEST’s testing suite, continuous testing becomes possible.

Your project’s developer and test engineer are working from the same script, the original application mock-up right out of the gate. While the development team focuses on code-writing, the testing group captures objects from the mock-ups and early development, allowing them to create and execute test scripts.


Writing individual scripts for multiple mobile platforms is tedious, time-consuming, and inefficient. That is where ZAPTEST shines. Write one script for all platforms, including Windows, macOS , Mobile: Android, and iOS. 

The suite of mobile tools
  • M-RUN Technology – allows parallel execution of a single test script across multiple mobile devices, expediting regression testing by including all devices.
  • ZAP Viewer – brings the ‘one script plays anywhere’ methodology to life, allowing the establishment of a connection with a remote workforce, so everyone is on the same page, whether working from a web-based or mobile connection.
  • Device Manager – offering complete control of all applications, reporting device status and history, pre-configuring apps, and even automatic device prep and setup.


Utilizing ZAPTEST’s 1SCRIPT technology, your team can automate testing across all the major browsers. Instead of tuning a test script for a particular browser, develop a single script and run it on just about any browser.

Supported Browsers

This proprietary technology is in line with ZAPTEST’s strategic and tactical vision for executing automated testing, and it requires no modification across:

All versions of Internet Explorer (IE/EDGE)
Et cetera


1SCRIPT doesn’t just create compatibility across browsers. It also automates your testing across native applications. Use the GUI Scan tool to capture objects, create a testing script, and execute it with mouse clicks.

Supported Platforms

You don’t have to be a computer programmer to harness the power of ZAPTEST across platforms like:

  • Mac OSX 
  • Linux
  • Windows
  • Unix

Freeing your business from platform dependencies is essential for maximizing the benefits of process automation. And ZAPTEST is the best software test automation tool for automated processes.


An application program interface (API) is essential for communication with both your internal and external partners and the teams that drive your innovation. Your data cannot be leveraged across your stakeholders without an integrated API, bogging all of your integration efforts. But it must also function within your user interface. 

ZAPTEST API Automation

That is where ZAPTEST’s API automation testing software comes in. It supports blending API and UI objects into a single script, enabling a single execution to test both the front and back ends of your application. It doesn’t get much more efficient than that, and the ZAPTEST API automation testing tool works with most major web service technologies, such as:

  • SOAP
  • WSDL
  • WADL
  • REST
  • XML
  • JSON 


All the best coding and app development in the world will fall flat on its face if it can’t meet the required performance demand. Utilize ZAPTEST’s load testing tools to measure the performance capacity of your API server in high-demand situations to make sure your infrastructure can scale up to meet the needs of your app and the consumers using it

Performance & Load Testing Automation with ZAPTEST’s Free Software

Load or Performance testing is an essential part of an application development lifecycle. ZAPTEST as the market leader in free and enterprise software testing and RPA provides all the necessary tools to develop a robust load-testing framework.
They allow ZAPTEST users to construct performance tests to answer critical questions about system performance and end-user experience:

  • Does the Application Under Test (AUT) respond quickly enough for intended users?
  • Can the System Under Test (SUT) handle the expected number of active users and beyond?
  • Can the SUT support the amount of transactions required by the business?
  • Will the AUT remain stable under expected or unexpected load conditions?
  • And most importantly will the users have a positive experience when the release goes live?

In a load testing framework real users are replaced with virtual users. Virtual users follow test script steps to mimic real users’ actions. Multiple virtual users can operate concurrently on the same host machine, and multiple hosts can be utilized to scale up the load.

A special type of test script is required for load testing. ZAPTEST allows scripts developed for API functional testing, or scripts recorded with the API Recorder Tool. Users can use this free performance testing tool to capture the communication between a Web Browser or Client Application and a Server. The captured information is then automatically converted to API objects and test steps.

A recorded script can be further enhanced by defining transactions, parameters, wait steps, verification points, and by correlating dynamic values.

The free API Correlation Manager Tool offers assistance in locating the values and defining correlation steps throughout the performance testing process.

Load test scripts often need to use complex and extensive test data. ZAPTEST’s free performance and load testing tools provide a test data management mechanism to supply the data values using different sources and different formats. The same mechanism ensures data allocation and distribution among users according to the business process rules.

The LOAD Studio free tool in ZAPTEST is a one-stop utility to construct and execute performance and load testing scenarios. The scenario design components help to define all load attributes – business processes, the number of users, test run duration, load configurations like slow ramp-up and ramp-down, Service-Level Agreement (SLA) or pass/fail criteria based on response times or errors. It offers an easy way to switch between test data sources and select the desired load generating host.

ZAPTEST’s free performance and load testing tools allow for multiple load generators to be configured on different servers at different locations. This helps to scale-up the number of users, and to imitate load from different locations or IP addresses.

During a test run ZAPTEST users can monitor basic load parameters and error logs.

The comprehensive results report uses HTML format and includes statistics and graphs for every step or transaction that was present in the test scripts. The report also lists all errors returned by the server, step, and transaction statuses according to Service Level Agreements. Each performance graph included in our free edition software offers drill-down features that help to reveal performance-related test issues.

Case Study

Michael runs IT & Digitalization for one of our (now) clients. He came to us with one challenge brought to him by Sam(head of procurement)who was manually performing a very large number of invoice processing tasks. They invest a lot of labour in these repetitive processes, but automating them would have required additional time, money, and expertise that the company did not have.

ZAPTEST automation was an ideal fit for this challenge, as it allows for seamless end-user processes through any digital interface regardless of Application Under Automation. As such, Zaptest, the IT and Procurement functions worked together and ultimately delivered a variety of high-performing scripts for RPA bots that took over more than 98% of daily executions. In practice, during the automated process, Sam’s Subject Matter Experts (SMEs) record ZAPTEST Video Scenarios used by Michael’s specialists for automation. They auto-generate documentation coverage and schedule bots for mass execution using multiple virtual workstations.

Unlike other available solutions, ZAPTEST doesn't require application instrumentation and executes AS-IS. Thanks to the collaboration with ZAPTEST, Michael’s team has moved into a centralized role within their organization, offering generalized TEST + RPA process automation that is now used by Dev/Test as well as Ops teams, saving the company over 70% of the operational budget.
