Licence registration is causing integration tests to fail

Question

Hi,We have some actions that make use of XlsIO.To test these actions, we have some integration tests in a separate project. We register our Syncfusion licence in both the App.xaml.cs constructor (of the production project) and at the beginning of the integration test in the tests project.We have noticed that some of the outputs generated by XlsIO are appended with "Created with a trial version of Syncfusion Essential XlsIO", causing our tests to fail. What is the recommended way to register Syncfusion for testing purposes?Thanks,Josh

Hi Josh, 

Greetings from Syncfusion.  

Syncfusion introduced the licensing system from v16.2.0.41 for Syncfusion NuGet packages and evaluation setup. We will validate the license key and include the Evaluation warning watermark in the output documents. However, you can remove this evaluation warning by registering license key in your application.    

Our license keys are version and platform specific. So, please generate and register the corresponding platform license key for the required version in your application by referring the below KB article.

Hi Keerthi,Yes I have already successfully registered my WPF program with a licence key.My question is how do I register Syncfusion from unit and integration tests? I try to register at the beginning of the test, but this does not work. [TestMethod]public void TestMethod(){     Syncfusion.Licensing.SyncfusionLicenseProvider.RegisterLicense("my licence key");     // A method in my application which uses Syncfusion XlsIO is called here}
