These tests make assertions against specific user-oriented output from the
"terraform init" command, but we've intentionally changed some of these
messages as part of introducing support for the decentralized provider
namespace.
We encourage users to share the "terraform version" output as part of
filing an issue, but previously it only printed the core Terraform version
and this left provider maintainers with no information about which
_provider_ version an issue relates to.
Here we make a best effort to show versions for providers, though we will
omit some or all of them if either "terraform init" hasn't been run (and
so no providers were selected yet) or if there are other inconsistencies
that would cause Terraform to object on startup and require a re-run of
"terraform init".
Two different errors here caused this test to pass even though it was
incorrect: the wanted version string was incorrect, but the test for it
was also inverted, and so together this made the test pass even though
it was actually not testing the output at all.
This basic test is here primarily because it's one of the few that can
run without reaching out to external services, and so it means our usual
test runs will catch situations where the main executable build is
somehow broken.
The version command itself is not very interesting to test, but it's
convenient in that its behavior is very predictable and self-contained.
