The test suite validates the assembler and B compiler across all target platforms. Tests compile, assemble, link, and compare runtime output against expected results.

Running Tests

cd tests
./run_tests.sh z80      # Z80 only (assembler + B language)
./run_tests.sh 8086     # 8086 only
./run_tests.sh 8086exe  # 8086 EXE only
./run_tests.sh 8080     # 8080 only
./run_tests.sh all      # All platforms
