Manual fail of task

[Narsimha1997]

I want to fail task when the command successfully executed and based on the output of the script.
example: i have python script having conditional task so when i run the script i should get according to the input so for my convenience i want to fail the task if output is not familiar,
so please suggest me that yaml syntax anyone?

Hi @Narsimha1997 👋

One possible way to accomplish this is with the following YAML code:

steps:
  - name: s1
    command: echo valid
    output: RESULT
  - name: s2
    command: "sh"
    script: |
      echo result=$RESULT
      if [ "$RESULT" != "valid" ]; then
          exit 1
      fi
    depends:
      - s1

I was thinking that it would be great to add more versatile condition capabilities, such as the ability to specify preconditions like the one in this example where we check if the result is not equal to "valid".

steps:
  - name: s1
    command: echo valid
    output: RESULT
  - name: s2
    command: "false" # fail
    preconditions:
      - condition: "$RESULT"
        predicate: "!="
        expected: "valid"
    depends:
      - s1
