During the development of chainlint.pl, numerous new self-tests were
created to verify correct functioning beyond the checks already
represented by the existing self-tests. The new checks fall into several
categories:
* behavior of the lexical analyzer for complex cases, such as line
splicing, token pasting, entering and exiting string contexts inside
and outside of test script bodies; for instance:
test_expect_success 'title' '
x=$(echo "something" |
sed -e '\''s/\\/\\\\/g'\'' -e '\''s/[[/.*^$]/\\&/g'\''
'
* behavior of the parser for all compound grammatical constructs, such
as `if...fi`, `case...esac`, `while...done`, `{...}`, etc., and for
other legal shell grammatical constructs not covered by existing
chainlint.sed self-tests, as well as complex cases, such as:
OUT=$( ((large_git 1>&3) | :) 3>&1 ) &&
* detection of problems, such as &&-chain breakage, from top-level to
any depth since the existing self-tests do not cover any top-level
context and only cover subshells one level deep due to limitations of
chainlint.sed
* address blind spots in chainlint.sed (such as not detecting a broken
&&-chain on a one-line for-loop in a subshell[1]) which chainlint.pl
correctly detects
* real-world cases which tripped up chainlint.pl during its development
