Let's try an invaild `TestAndSet` command.
We can give another parameter prevValue to set command to make it a TestAndSet command.
```sh
curl http://127.0.0.1:4001/v1/testAndSet/testAndSet -d prevValue=two -d value=three
curl http://127.0.0.1:4001/v1/keys/testAndSet -d prevValue=two -d value=three
```
This will try to test if the previous of the key is two, it is change it to three.
```html
Test one==two fails
```json
{"errorCode":101,"message":"The given PrevValue is not equal to the value of the key","cause":"TestAndSet: one!=two"}
```
which means `testAndSet` failed.
