    Description

      The declarative pipeline documentation on "post" says the following: "These condition blocks allow the execution of steps inside each condition depending on the completion status of the Pipeline or stage" 

      Currently, the post execution of a stage seems to refer to the whole pipeline status at that point and not the completion status of the stage as documented.

      Given the following pipeline:

      pipeline {
        agent any
        stages {
          stage('First') {
            steps { echo 'Hello' }
            post { success { echo 'First stage is success' } }
          }
          stage('Second') {
            steps { sh """ echo '<testsuite errors="1" failures="0" name="test" skipped="0" tests="1" time="1"><testcase classname="" file="file.txt" name="name" time="0.000"><error message="error"></error></testcase></testsuite>' > test-results.xml """ }
            post {
              always { junit 'test-results.xml' }
              unstable { echo 'Second stage is unstable' }
            }
          }
          stage('Third') {
            steps { echo 'Hello' }
            post {
              success { echo 'Third stage is success' }
              unstable { echo 'Third stage is unstable! really???' }
            }
          }
        }
        post { unstable { echo 'Job is unstable' } }
      }
      
      

      I get the following output:

      [Pipeline] {
      [Pipeline] stage
      [Pipeline] { (First)
      [Pipeline] echo
      Hello
      Post stage
      [Pipeline] echo
      First stage is success
      [Pipeline] }
      [Pipeline] // stage
      [Pipeline] stage
      [Pipeline] { (Second)
      [Pipeline] sh
      + echo <testsuite errors="1" failures="0" name="test" skipped="0" tests="1" time="1"><testcase classname="" file="file.txt" name="name" time="0.000"><error message="error"></error></testcase></testsuite>
      Post stage
      [Pipeline] junit
      Recording test results
      [Pipeline] echo
      Second stage is unstable
      [Pipeline] }
      [Pipeline] // stage
      [Pipeline] stage
      [Pipeline] { (Third)
      [Pipeline] echo
      Hello
      Post stage
      [Pipeline] echo
      Third stage is unstable! really???
      [Pipeline] }
      [Pipeline] // stage
      [Pipeline] stage
      [Pipeline] { (Declarative: Post Actions)
      [Pipeline] echo
      Job is unstable
      [Pipeline] }
      [Pipeline] // stage
      [Pipeline] }
      [Pipeline] // node
      [Pipeline] End of Pipeline
      

      Clearly the third stage post unstable block is executed even though the stage itself is a success.

      This is also contradicted by the blue ocean stage view:
