…ing and adds DoNotParallelize
Two bugs in DistributedTransactionTests.cs:
1. Mock JSON used all-lowercase property names ('statuscode', 'substatuscode',
'resourcebody') that do not match the model's JsonPropertyName attributes
('statusCode', 'subStatusCode') or the manual TryGetProperty lookup
('resourceBody'). System.Text.Json deserialization is case-sensitive, so
StatusCode was always 0 causing all status-code assertions to fail.
2. Missing [DoNotParallelize] attribute. The TestInitialize calls TestInit()
which runs DeleteAllDatabasesAsync; without [DoNotParallelize] concurrent
test execution causes emulator resource contention (same fix as #5711 for
the predecessor class DistributedTransactionE2ETests).
Also removes stray 'git' text from an inline comment.

Summary
Adds
[DoNotParallelize]attribute toDistributedTransactionE2ETeststo prevent concurrent test execution contention on the emulator.Root Cause
All 4 tests share a
TestInitializethat creates a new container viaBaseCosmosClientHelper.TestInit()(which callsDeleteAllDatabasesAsync). Concurrent test execution caused resource contention on the emulator, resulting in consistent ~4% failure rate across all 4 tests.Tests Fixed (95.82% pass rate each — 16 failures each in 30 days)
