// test bug 1355539.
//
// Summary:
// Transactions in one pending queue are splited into two groups:
// [(Blocking Group)|(Non Blocking Group)]
// In each group, the transactions are ordered by its priority.
// This test will check if the transaction's order in pending queue is correct.
//
// Test step:
// 1. Create 6 dummy http requests. Server would not process responses until get
// all 6 requests.
// 2. Once server receive 6 dummy requests, create another 6 http requests with the
// defined priority and class flag in |transactionQueue|.
// 3. Server starts to process the 6 dummy http requests, so the client can start to
// process the pending queue. Server will queue those http requests and put them in
// |responseQueue|.
// 4. When the server receive all 6 requests, check if the order in |responseQueue| is
// equal to |transactionQueue| by comparing the value of X-ID.
