… references The GetFormattedExceptionMessage method in ExceptionHelper.cs recursively traverses the inner exceptions of an exception to build a formatted error message string. However, it did not handle the case where the inner exceptions have a cyclic reference, causing an infinite loop. This change fixes that issue by keeping track of the exceptions seen during traversal in a HashSet. If an exception is encountered again, it breaks out of the loop and appends a "[Cyclic Exception Reference]" message to the output, avoiding the infinite recursion. The key changes are: Introduce a HashSet seenExceptions to keep track of exceptions encountered so far. Check if the current exception has already been seen. If so, append a "[Cyclic Exception Reference]" message and break out of the loop. If the current exception hasn't been seen, add it to the seenExceptions set and continue processing as before. A new test class ExceptionHelperTests has also been added with two test methods: GetFormattedExceptionMessage_WithCyclicExceptions_ShouldNotLoopInfinitely - Verifies that cyclic exceptions are handled correctly and don't cause infinite loops. GetFormattedExceptionMessage_WithNoCyclicExceptions_ShouldFormatNormally - Ensures that the normal formatting still works as expected for non-cyclic exceptions. This fixes microsoft#1234 Files changed: src/Adapter/MSTest.TestAdapter/Execution/ExceptionHelper.cs test/UnitTests/MSTestAdapter.UnitTests/Execution/ExceptionHelperTests.cs
