 # performance-testing
 The code from my YouTube video on "How to do Performance Testing with k6"
+
+You first need to run the API:
+```sh
+cd src
+dotnet run
+```
+
+Then in a seperate terminal window run the tests using the commands below.
+
+I have added a HOSTNAME variable to each of the scripts (except simple-test.js) which needs to be added when running them.
+
+## Stress Test
+```sh
+k6 run -e HOSTNAME=localhost:5157 tests/stress-test.js
+```
+
+## Spike Test
+```sh
+k6 run -e HOSTNAME=localhost:5157 tests/spike-test.js
+```
+
+## Load Test
+```sh
+k6 run -e HOSTNAME=localhost:5157 tests/load-test.js
+```
+
+## Soak Test
+```sh
+k6 run -e HOSTNAME=localhost:5157 tests/soak-test.js
+```
