But it’s more tricky to define how many times your API will be executed in your running application or what is as reasonable response time. It’s probably easier to define in advance the number of users that will work with the system and the expected response time for a specific user transaction. In such cases, use WebLOAD’s XML and JSON parsers, which converts the structures to simple structures, making validation easy. But in cases where the request or the response are XML or JSON, it may be tricky to deal with its structures. It is quite easy to validate simple values. Using WebLOAD’s Parameterization Manager you can feed different values and hold different responses to be validated easily. Therefore, you should build tests with many different parameters to validate the various responses. Your API receives parameters and returns values. Whether you are using an open source integrated in your application or you remotely use 3rd party API – you need to load test these APIs as well to make sure they adhere to your requirements. In many cases you’ll be using 3rd party tools and APIs. WebLOAD can record your API request, simply by recording your HTTP/HTTPS traffic. You can record the API using an application that uses the API or using one of the API testings tools such as Postman, Boomerang, Advanced REST client, etc. In most cases you’ll write the test (rather than record) since typically you will not have written yet the request to your new API in your application. You can use WebLOAD’s SOAP and REST wizards, or you can code the HTTP requests on your own in JavaScript. Building an API request in WebLOAD can be done in 2 ways: Using Wizard or via Recording. With WebLOAD you can test all types of APIs, whether they are REST or SOAP. Start with the basics and create a test for each API. So where does one start? Ideally – by downloading and reading this eBook – Load Testing Buyer’s Guide, but if you’re just interested in the “Nutshell” version, here are five tips to handle this testing goal efficiently. In terms of performance testing, this translates to the need to continuously load test your API, WSDL, and REST code. Nevertheless, also newly-developed API are doomed to be changed in future iterations for various reasons. These can later be used in future development cycles. There’s simply a perfect fit in the development approach – rather than engage in long development processes of full features, small components are developed and are packaged in an API. Web Services have been known for years, but have become popular once agile and DevOps took off. ![]()
