Amazon Simple Storage Service (S3) – to host the latest/modified code for the tool so that it can be pulled into the EC2 instances upon launch and a medium for the launcher tool to listen and act ontrol.Amazon Elastic Compute Cloud (EC2) – to launch instances of the clients.Amazon Chime SDK – to support Amazon Chime SDK for JS clients.These are the permissions that will be added: Once the AWS CloudFormation Stack is setup using the CDK script provided in the package, the necessary AWS Identity and Access Management (AWS IAM) policies are automatically set up. The app should be compatible to run on Google Chromium based browsers.Ĥ. Alternatively, you can deploy a serverless version of the same using the guide mentioned here. ![]() Build a client using the Amazon Chime SDK for JS and host it on the internet. ![]() App built using the Amazon Chime SDK for JS Set up and install AWS CLI in the local machine by following the instructions mentioned here.ģ.AWS Command Line Interface on the local machine Set up and install Node JS in the local machine by following the instructions mentioned here.Ģ.The developers can add custom scenarios to the load test tool by writing a custom methods in the ClientController class and invoking it in the performActivity() of the ChildActivity. Some scenarios that can be already tested using the tool are: The tool can also help simulate different scenarios on each individual attendee dynamically while a load test is active. Simulate different scenarios on client app The Amazon Chime SDK client launcher tool can help builders and developers launch their application to start multiple test meetings with multiple participants, collect metrics on these tests to understand how the application can be optimized for a better user experience.Įxample: The tool can be used to monitor the average time taken for the clients to launch on a browser or track how long it takes for the audioVideoDidStart() to get triggered. Optimize Amazon Chime SDK for JS client app The Amazon Chime SDK client launcher tool can help builders and developers launch their application to start a meeting with multiple participants and observe how the app behaves. Here are some scenarios the tool is designed to support: Simulate attendees in a meeting The features of each client can be dynamically controlled while a load test is active. It simulates real attendees by launching test Amazon Chime SDK for JS clients, each in a new browser tab. The Amazon Chime SDK client launcher tool eliminates the need for humans to join as participants in a meeting in order to test features and functionalities of applications built using the Amazon Chime SDK for JS. Note: Deploying the demos created in this post can incur AWS charges. The tool can be used for the following scenarios:Ī) test your app with large number of participants orī) test multiple independent sessions of your app We provide an open-source tool, the Amazon Chime SDK client launcher tool, to simplify your approach. ![]() In this blog, we will teach you how to test applications built with the Amazon Chime SDK for Javascript (Amazon Chime SDK for JS) at scale under a variety of load conditions. To overcome this issue, we have built a solution to let the builders test their application with a large number of attendees without needing actual people. Builders creating audio-video communication applications can find it challenging to load test using a large number of attendees because of the challenges with inviting large number of unique individuals to join a meeting.
