Postman Load testing

This is a proof of concept for taking API calls using the Postman collections to quickly perform load testing on software environments.

Prerequisties

• Postman Installation
• Install Grafana K6

Sample DotNet API

1. Download .Net and installation docs.
   • macOS note: use installer
2. Create folder "TaskSample" and inside, solution file dotnet new sln.
3. Create class library dotnet new classlib -n TaskSample.Tasks.
4. Add library to the solution dotnet sln add TaskSample.Tasks/TaskSample.Tasks.csproj
5. Build the solution dotnet build TaskSample.sln
6. Run unit tests dotnet test
7. Add library to expose as an api dotnet new webapi -minimal -o TaskApi
8. Add reference to Task project dotnet add reference ../Task/Task.csproj
9. dotnet dev-certs https --trust
10. dotnet run --project TaskApi/TaskApi.csproj
11. https://localhost:7053/swagger/index.html (test weather)
12. remove weather and add method for Task API
13. update .gitignore file with dotnet new gitignore --force
