hyppotest
Hyppotest is a tool @Paul Gardner-Stephen introduced into the mega65-core
repo to run a suite of automated tests on the hypervisor.
Source-code is located at
src/tools/hyppotest.c
Can be built from the base of
mega65-core
repo withmake src/tools/hyppotest
To run the tool, just provide the name of a test-script to execute, e.g.:
./hyppotest hyppotest-self.test
[PASS] assemble with acme
[PASS] poke directive
[PASS] check mem
[PASS] ignore reg directives
[PASS] clear breakpoint directives
[PASS] step and run directives
[PASS] let directive
[ ] flag directivesAborted (core dumped)
Jimbo has made improvements in this PR which has been merged into development branch:
I’ll paste the details he shared there into here, as a starting point for documentation on this tool:
Enhancements
The lines of hyppotest test files can be freely indented with initial whitespace.
hyppotest can run just a specific test in a test file.
hyppotest can take a 2nd optional command-line argument, which is the name of a test in the test file.
When this 2nd argument is present, hyppotest only runs the named test. hyppotest ignores any other tests in the test file.
hyppotest can test the CPU flags as the F register.
The instruction log's capacity has been doubled.
hyppotest can execute and disassemble all (officially documented) 6502 and 65C02 opcodes.
Additional test files
src/tools/hyppotest-self.test
tests some of hyppotest's directives.src/tools/hyppotest-opcodes.test
tests hyppotest's (officially documented) 6502 and 65c02 opcodes.Decimal mode is not tested.
This runs the 6502 and 65c02 test suites developed by Klaus Dormann (Klaus2m5).
There is a fork of this work for building these test suites so they're suitable for hyppotest.
This code has a GPL 3 license, so it can't be incorporated directly into this project.
Prebuilt bin and lbl files are available from Releases · jimnicholls/6502_65C02_functional_tests .
New test directives
There are new directives for use in hyppotest test files.
allow stack <overflow|underflow>
assemble [at <address|symbol>] with acme
check regs
synonym for check registers
check <mem|memory>
synonym for check ram
clear all breakpoints
clear breakpoint (address|symbol)
clear flag flag
define name as value
end assemble
end test
synonym for test end
expect flag flag is <clear|set>
forbid stack <overflow|underflow>
let reg = value
Presets the value of a register
poke <address|symbol>, value[, value…]
ignore reg name
Excludes the named register from the check registers directive.
ignore all regs
run until <brk|jsr>
set flag flag
step [count]
Fixes
For the jmp and jsr directives:
arguments like $nnnn are interpreted as literal addresses; and
symbols can be either hyppo or non-hyppo symbols.
Negative symbol deltas (eg sym-16 or sym-$0a) calculate the correct address.
make clean
deletes the tool binaries that had been built and the FAIL and PASS files output by hyppotest.Git ignores the FAIL and PASS files output by hyppotest.
hyppotest consistently writes to the simulated ram and leaves the expected ram for the expect and check directives.
A test fails if any of the directives in the test fail.
The base register is set to 0 when hyppotest starts execution outside the hyppo.
When hyppotest can't read the test file, the error message from hyppotest includes the name of the test file.
hyppotest shows addresses that exactly match a symbol as that symbol.
