Test your function

Let's get Trigger URL by clicking the function name and go to Trigger tab.

You can test the endpoint using curl

curl --location --request POST '<your_trigger_url>' \
--header 'Content-Type: application/json' \
--data-raw '{
    "executable": "IyEvdXNyL2Jpbi9lbnYgcHl0aG9uMwoKaW1wb3J0IHN5cwoKZGVmIG1haW4oZGF0YSk6CiAgICByZXR1cm4gZGF0YQoKCmlmIF9fbmFtZV9fID09ICJfX21haW5fXyI6CiAgICB0cnk6CiAgICAgICAgcHJpbnQobWFpbigqc3lzLmFyZ3ZbMTpdKSkKICAgIGV4Y2VwdCBFeGNlcHRpb24gYXMgZToKICAgICAgICBwcmludChzdHIoZSksIGZpbGU9c3lzLnN0ZGVycikKICAgICAgICBzeXMuZXhpdCgxKQo=",
    "calldata": "\"Hello lambda\"",
    "timeout": 3000
}'

The expected result should be:

{
    "returncode": 0,
    "stdout": "Hello lambda\n",
    "stderr": "",
    "error": "",
    "version": "google-cloud-function:1.1.2"
}
