Lately we've made some changes that have affected the behavior of the specsuite tests, causing them to fail. Much of this was caused by changes to the harness itself (based on hcldec), although one break in particular here was an intentional change to the implementation of modulo in upstream cty to make it produce a more accurate result when used with a fractional divisor. |

HCL Language Test Suite
This directory contains an implementation-agnostic test suite that can be used to verify the correct behavior not only of the HCL implementation in this repository but also of possible other implementations.
The harness for running this suite -- a Go program in this directory -- uses
the hcldec
program as a level of abstraction to avoid depending directly on
the Go implementation. As a result, other HCL implementations must also
include a version of hcldec
in order to run this spec.
The tests defined in this suite each correspond to a detail of the HCL spec. This suite is separate from and not a substitute for direct unit tests of a given implementation that would presumably also exercise that implementation's own programmatic API.
To run the suite, first build the harness using Go:
go install github.com/hashicorp/hcl/v2/cmd/hclspecsuite
Then run it, passing it the directory containing the test definitions (the
"tests" subdirectory of this directory) and the path to the hcldec
executable
to use.
For example, if working in the root of this repository and using the hcldec
implementation from here:
go install ./cmd/hcldec
hclspecsuite ./specsuite/tests $GOPATH/bin/hcldec
For developers working on the Go implementation of HCL from this repository,
please note that this spec suite is run as part of a normal go test ./...
execution for this whole repository and so does not need to be run separately.
