fix(spec): correct assertion for metatable with __metatable=nil
|
|
|
|
A test case in `spec/inspect_spec.lua` was failing when run with
|
|
LuaJIT on aarch64. The test checks the behavior of `inspect` on
|
|
tables with metatables that have the `__metatable` field set.
|
|
|
|
The failure occurred for the case where `__metatable` was set to
|
|
`nil`. The `inspect` function correctly hides the metatable in
|
|
this scenario, as `getmetatable` returns `nil`. However, the test
|
|
was expecting the metatable to be displayed, and with incorrect
|
|
content, causing the assertion to fail.
|
|
|
|
This commit corrects the failing assertion to expect the correct
|
|
output from `inspect`, which is an empty table string `'{}'`.
|
|
This aligns the test with the documented behavior of Lua's
|
|
`getmetatable` and the current implementation of the library.
