The 179K polyline records of USGS Roads data in WGS 1984 Web Mercator (Auxiliary_Sphere), equates to about 200MB when zipped. The spatial size of the data source also needs to be large enough to generate decent test data but not too big where it is cumbersome to download.Įnter in the Motor Vehicle Use Map: Roads feature layer dataset on . But this repeatability requires access to the same set of data. The understanding of the process in this Article is most effective if the steps can be reproduced.

How to Test a Hosted Feature Service? The USGS Motor Vehicle Use Roads Dataset Couple this with the fact that each query request in the transaction will have a unique geometry and changing maxAllowableOffset (depending on the map scale) and its a lot of moving parts to keep track of. To repeat this behavior, the constructed load test will not have just one request to issue but many and a varying amount. A navigational "pan" or a "zoom" in the web browser produces a handful of different queries, each with their own geometry. Hosted Feature Layer Service Testing ChallengesĬompared to testing the export map function, testing Hosted Feature Layer Service queries is challenge as the requests are more complex to achieve programmatically. Given that hosted feature services are a proven and favorite service technology, it makes sense to want to test feature queries under load to observe its scalability first hand. Couple this with client-side rendering of the data returned and its a win-win. Additionally, querying these layers are based on a "repeated" grid design which can help provide a higher degree of scalability over other visualization technologies. However, Hosted (feature) layers are also a popular capability of ArcGIS Enterprise and are widely used in deployments.

The bulk test data can be added manually in User Parameters, but it is time-consuming. Since there is only one value can be given in User Variables so bulk test data can not be used.Test Data cannot be added via an external file in User Parameters and User Defined Variables whereas CSV Data Set Config use.In User Defined Variables, there is only one value of the variable can be defined whereas, in User Parameters and CSV Data Set Config, multiple values can be defined for a variable.User Parameter is a preprocessor whereas CSV Data Set Config and User Defined Variables are Config Elements.What is the difference between User Parameter, User Defined Variable and CSV Data Set Config? User Variables can also be defined in the Test Plan using ‘ User Defined Variables‘ but those are not specific to individual threads. A set of parameters get reused in case less number of data than the number of threads.
As I mentioned, when you have less number of test data then you can easily insert the values in the User Parameter field and allow threads to share the test data. In JMeter, ‘User Parameters’ preprocessor can be used when you have less number of test data which can be used in a repetitive manner and shared by all the thread.
This element is used to define the user (thread) specific parameters, although the CSV Data Set Config is an easy and flexible method for parameterization.
