Apache jmeter jdbc how to#

That’s it! You now know how to do faster API testing with JMeter by retrieving data from the database to your local machine. The general view of the test scenario will have the form shown in the image below: The View Results Tree allows you to display each sent request and the results. In the BeanShell Assertion, add the following example code:īoolean comparisonResult = false for ( int i i Add -> Listener -> View Results Tree Dummy Sampler -> Add -> Assertions -> BeanShell Assertion. null - if the value of the parameter 'cityName' from the API response is not received, the variable cityNameFromApi will be set to 'null'Ĩ.1 means that it is necessary to use the first value to be obtained by the regular expression.Jp - Dummy Sampler # 1 - is a regular expression that gets the value of the 'cityName' parameter from the API response In the 'JDBC Request' add the following example code:

Configure the connection to the database.Ģ. To run this script, you need to do the following:ġ. This will reduce the number of requests in the database and the time to run the tests. The data from the database that is used to verify that the API returned a correct answer, will be retrieved once, before the tests begin. We will perform 5 API tests with JMeter with the following values of 'city_id': 1,2,3,4,5. How to Retrieve Database Data For API Testing With JMeter Table 'city' Suppose that we have an API that takes the parameter 'city_id' and according to the value of this parameter, the API returns the parameter 'cityName' = 'city' from the table 'city'. In addition to API testing, JMeter is also very popular for performance testing, load testing, and stress testing. Second, JMeter can be used with any platform that has a JVM, such as Windows, Linux, and macOS, since it is based on Java. First, it is an open-source solution with many plugins to help with performance and load testing. There are many benefits to doing API testing with JMeter. How to Retrieve Database Data For API Testing With JMeter.This blog post will show you how to do that by using Apache JMeter™. If such cases occur during testing, a possible solution is to retrieve data from the database onto our local machine just once and use it for all the tests you need to perform for the API. In such a case, we will get a negative result, because the database will not allow us to connect. It also often happens that the database has a limited number of connected users and running execution tests that can address the database. The data samples that need to be tested in the database can be either simple or complex, which leads to an increase in the time required to run the tests. When performing API testing with JMeter, we always have to go to the database to check the values that the tested API returns.
