`test.sh`

POSIX compliant, TAP producing,
`sh(1)`

testing library

## Usage

```
#!/bin/sh
. ./test.sh
test "one plus zero is zero"
sum=$((1+0))
[ $sum -eq 0 ]
test "one plus one is two"
sum=$((1+1))
[ $sum -eq 2 ]
test "one plus one is three"
sum=$((1+1))
[ $sum -eq 3 ]
test "two plus two is four"
sum=$((2+2))
[ $sum -eq 4 ]
```

## Output

```
not ok 1 - one plus zero is zero
ok 2 - one plus one is one
not ok 3 - one plus one is three
ok 4 - two plus two is four
1..4
```

## Notes

Overriding the `test(1)`

command is intentional and using the alternate
`[`

form is recommended in tests.

## Known issues

Due to the fact that the previous test is computed on the next `test`

call, the output from the current test(if any) is shown before its
message.
