Read this before Selecting a Performance Testing Tool for App Development

In this article, we are going to talk about how to select a performance testing tool for your software project which can tick all the necessary checkboxes in practical scenarios. Read till the end to learn more.


The first and most important requirement during the planning stage is to select the appropriate performance testing tool. You must choose a performance testing solution that satisfies the performance targets after knowing the application architecture and business needs. Without performing a POC (proof of concept), you cannot say which tool is the best because each tool has advantages and disadvantages. 

Some clients insist on using the best open-source technology to avoid the additional costs associated with buying a tool since they do not have enough money to cover the license fees. Again, there are a lot of open-source tools available, so choosing the best one is difficult. That is why we have posted this article to assist you as we break down the criteria you should know before selecting a performance tool:

1. Integration with Other Tools:

The CI/CD approach in the DevOps sector makes use of numerous tools to automate end-to-end processes. The ability to integrate with other tools is an extremely important requirement for the performance testing tool. Additionally, the integration process shouldn't be laborious or complicated. This is why we recommend using testing solutions from Wetest where you will have integration support with the most popular CI/CD tools of the industry that trigger automated tests with each build action. 

2. Cost

Money has to be considered as it correlates to the project spending. The client's budget will determine this very important variable. Based on price, performance testing tools can be divided into these groups:

Licensing: Depending on the needs of the client or the project, you must purchase the license for such tools. The license packages are determined by the number of users or kind of protocol. A fully functional set of scripting, test execution, and result-analysis tools is included in a licensed utility.

Open-source: Is it a performance-checking tool that may be used for free and offers scripting, scenario design, test execution, and resource monitoring? If yes then it’s a great option.

Cloud-based: This type of hybrid performance-checking tool only charges when the test is run by producing the required load. The test script can be created using an open-source tool, uploaded to the cloud, and then executed. These tools cost less than licensed performance tools.

3. Support Team:

Googling your problems for testing software is never better than a dedicated support team, so choose a solution with adequate operational support instead. This race is always won by licensed tools. There should be a proper issue management and tracker system where you can raise a ticket or chat with the team. Having a tool support staff is not sufficient on its own. These options aid in meeting project deadlines and helping to resolve the problem as promptly as possible. If you have a knowledgeable staff using open-source software, go for it and cut the project's costs.

4. Response Validation

The capability to confirm the accuracy of the response given during the test must be provided by the performance-checking tool. In normal routines, it has been observed that functional problems that surface during the performance test are usually caused by the absence of this feature.

5. Feature Pack:

The tool should have certain features which we think are a must. For example, to capture business flows, the tool must provide a recording option. For web application programming, the recording capability is useful, and 80% of AUTs fall into this group. This parameter is not necessary if the only requirement is to test the APIs. 

The parameterization option is necessary to feed the user inputs, such as the user name and password. The definition of variables, the use of plain text files, CSV files, or direct database querying can all be used to provide parameter values.

It is necessary to monitor the test in real time to check the number of active users, transaction rate, request rate, errors, etc. Although some open-source tools don't offer live monitoring, they can still be integrated with other tools to obtain real-time statistics.

Another feature that should be there in the tool you are going to select is to assess the test results. The tool must have the ability to present the results in a variety of formats, such as a graph, table, chart, etc. The filter option aids in focusing the investigation to locate bottlenecks. Graph merging is a feature that can be added to the result analyzer. A performance tester can avoid creating a manual report by using the report-generating option. Some tools allow you to create reports in a variety of formats, including PDF, DOC, CSV, and HTML.

Wrapping Up:

This article talked about performance testing tools and some fundamental criteria that you can use to select the tool that best suits your needs. and when it comes to serving the best industrial needs, nobody does it better than WeTest with a price tag one cannot ignore.
