dimensionValue property

If the execution containing this step has any dimension_definition set, then this field allows the child to specify the values of the dimensions.

The keys must exactly match the dimension_definition of the execution. For example, if the execution has dimension_definition = ['attempt', 'device'] then a step must define values for those dimensions, eg. dimension_value = ['attempt': '1', 'device': 'Nexus 6'] If a step does not participate in one dimension of the matrix, the value for that dimension should be empty string. For example, if one of the tests is executed by a runner which does not support retries, the step could have dimension_value = ['attempt': '', 'device': 'Nexus 6'] If the step does not participate in any dimensions of the matrix, it may leave dimension_value unset. A PRECONDITION_FAILED will be returned if any of the keys do not exist in the dimension_definition of the execution. A PRECONDITION_FAILED will be returned if another step in this execution already has the same name and dimension_value, but differs on other data fields, for example, step field is different. A PRECONDITION_FAILED will be returned if dimension_value is set, and there is a dimension_definition in the execution which is not specified as one of the keys. - In response: present if set by create - In create request: optional - In update request: never set
