Executing a Singularity Test fails

[sylabskeith-zz]

Version of Singularity:

2.4.2

Expected behavior

BootStrap: docker
From: alpine:latest

%test
[[ -z "$THIS_IS_A_TEST" ]] && echo "Environment is not loaded." >&2
echo "test: THIS_IS_A_TEST=$THIS_IS_A_TEST"

%runscript
[[ -z "$THIS_IS_A_TEST" ]] && echo "Environment is not loaded." >&2
echo "runscript: THIS_IS_A_TEST=$THIS_IS_A_TEST"

%post
apk update
apk add bash
echo 'export THIS_IS_A_TEST=TRUE' >> /environment

###Actual Behavior

1. The environment is not loaded before test during bootstrap
2. Singularity test command is failing with this msg: "No Singularity tests for contained app:"

Hi @sylabskeith

2. is fixed by the Fix test check #1335 that was merged into the 2.4.3 release:

$ singularity test test.img
test: THIS_IS_A_TEST=TRUE

1. is not - the environment is not loaded for test during build:

Running test scriptlet
+ [[ -z  ]]
+ echo Environment is not loaded.
Environment is not loaded.
+ echo test: THIS_IS_A_TEST=
test: THIS_IS_A_TEST=

This is by design from a change implemented in #1071 where the rationale was discussed in #1053 - environment is no longer sourced during the build.

@sylabskeith - closing this as the fix for behaviour (2) has been merged, and (1) is by design, as above. Let us know if any further issue. Thanks.
