      Problem
      If you have a parallel declaration, but no stages, in classic stage view nothing shows up (you just have to look at log). In blue ocean, you get a single node (stage) which shows only the first branch.
      Expected behavior: should show 3 parallel branches (ideally)

      Example

      parallel 'branch1': {
              node('node1') {
                  stage('Setup') {
                      checkout([details removed])
                  }
                  stage('Unit and Integration Tests') {
                      bat '"my command to execute tests"'
                  }
              }
      }, 'branch2': {
              node('node2') {
                  stage('Setup') {
                      checkout([details removed])
                  }
                  stage('Unit and Integration Tests') {
                      bat '"my command to execute tests"'
                  }
              }
      }
      

      Workaround
      Simply wrap the parallels in a stage and it will work correctly.

      stage('Build and Test') {
        parallel 'branch1': {
                node('node1') {
                    stage('Setup') {
                        checkout([details removed])
                    }
                    stage('Unit and Integration Tests') {
                        bat '"my command to execute tests"'
                    }
                }
        }, 'branch2': {
                node('node2') {
                    stage('Setup') {
                        checkout([details removed])
                    }
                    stage('Unit and Integration Tests') {
                        bat '"my command to execute tests"'
                    }
                }
        }
      }
      

      It will then be visualised like:

      Other examples

      Parallel defined between stages but not nested in its own stage

      node {
      	stage('Checkout') {
      		checkout scm
      	}
      }
      
      parallel linux: {
      	node('Linux') {
      		stage('Build') {
      			echo 'Build linux'
      		}
      		stage('Tests') {
      			echo 'Tests linux'
      		}
      		stage('Static analysis') {
      			echo 'Static analysis linux'
      		}
      	}
      },
      windows: {
      	node('Windows') {
      		stage('Build') {
      			echo 'Build windows'
      		}
      		stage('Tests') {
      			echo 'Tests windows'
      		}
      		stage('Static analysis') {
      			echo 'Static analysis windows'
      		}
      	}
      }
      

      Result looks like this:
