Struct MockExecutor

source 
pub struct MockExecutor {
    chunks: VecDeque<DataChunk>,
    schema: Schema,
    identity: String,
}
Expand description

Mock the input of executor. You can bind one or more MockExecutor as the children of the executor to test, (HashAgg, e.g), so that allow testing without instantiating real SeqScans and real storage.
