Feature: Inject a RemoteConfig instance into a mutable subcommand (invoke constructor)

  Scenario: RemoteConfig is injected successfully using defaults
    Given the user supplies no values for the context, deployment, or namespace
    When the RemoteConfig is injected into a mutating subcommand
    Then context will default to K8:this.kubeConfig.currentContext
    And namespace will default to LocalConfig.currentDeploymentName
    And cluster will be retrieved from LocalConfig based the context to cluster mapping
    And the RemoteConfig read is called and return true [depends on #771]

  Scenario: RemoteConfig is injected successfully
    When the RemoteConfig is injected into a mutating subcommand
    And namespace is provided by the user
    And one cluster is retrieved from the LocalConfig.deployments.clusters[]
    And one context is retrieved from the LocalConfig.clusterMappping[cluster]
    Then the RemoteConfig read is called and return true [depends on #771]

  Scenario: RemoteConfig is injected with namespace and LocalConfig.currentDeploymentName of null
    Given the RemoteConfig is injected into a mutating subcommand
    When the user provided namespace is null
    And the LocalConfig.currentDeploymentName is null
    Then RemoteConfig throws an error explaining that the deployment and namespace cannot be null

  Scenario: RemoteConfig is injected with cluster as null
    Given the RemoteConfig is injected into a mutating subcommand
    And the deployment is retrieved from either the user provided namespace or LocalConfig.currentDeploymentName 
    When the user provided cluster is null
    And the LocalConfig.deployments.clusters[] retrieved for the deployment is empty
    Then RemoteConfig throws an error explaining that a deployment and at least one cluster is needed to continue

  Scenario: RemoteConfig is injected with context as null
    When the RemoteConfig is injected into a mutating subcommand
    And the deployment is retrieved from either the user provided namespace or LocalConfig.currentDeploymentName 
    And the cluster is retrieved from the user or the LocalConfig.deployments.clusters[]
    And the context is null when retrieved from the cluster mapping
    Then RemoteConfig throws an error explaining that a context must be mapped to the deployment/cluster combination, displaying them to the user in the error message

  Scenario: RemoteConfig is injected and fails the read
    When the RemoteConfig is injected into a mutating subcommand
    And the deployment is retrieved from either the user provided namespace or LocalConfig.currentDeploymentName 
    And the cluster is retrieved from the user or the LocalConfig.deployments.clusters[]
    And the context is retrieved from the cluster mapping
    And the RemoteConfig read from k8s for the namespace/cluster/context fails
    Then RemoteConfig throws an error explaining if no file was found or if the file was found but failed to download successfully

  Scenario: RemoteConfig is injected, reads successfully, and validates as true
    When the RemoteConfig is injected into a mutating subcommand
    And the deployment is retrieved from either the user provided namespace or LocalConfig.currentDeploymentName 
    And the cluster is retrieved from the user or the LocalConfig.deployments.clusters[]
    And the context is retrieved from the cluster mapping
    And the RemoteConfig read from k8s for the namespace/cluster/context succeeds
    And the validate method is called and returns true (stubbed to return true for now)
    Then RemoteConfig was injected successfully

  Scenario: RemoteConfig is injected, reads successfully, and validates as false
    When the RemoteConfig is injected into a mutating subcommand
    And the deployment is retrieved from either the user provided namespace or LocalConfig.currentDeploymentName 
    And the cluster is retrieved from the user or the LocalConfig.deployments.clusters[]
    And the context is retrieved from the cluster mapping
    And the RemoteConfig read from k8s for the namespace/cluster/context succeeds
    And the validate method is called and returns false (mocked to return false)
    Then RemoteConfig failed to inject successfully
