+# Developing
+
+## Getting started
+
+In order to test and develop in this repo you will need the following dependencies installed:
+- docker
+- make
+
+After cloning do the following:
+1. run `make bootstrap` to download go mod dependencies, create the `/.tmp` dir, and download helper utilities.
+2. run `make` to run linting, tests, and other verifications to make certain everything is working alright.
+
+Checkout `make help` to see what other actions you can take.
+
+The main make tasks for common static analysis and testing are `lint`, `lint-fix`, `unit`, `integration`, and `cli`.
+
+## Levels of testing
+
+- `unit`: The default level of test which is distributed throughout the repo are unit tests. Any `_test.go` file that 
+  does not reside somewhere within the `/test` directory is a unit test. Other forms of testing should be organized in 
+  the `/test` directory. These tests should focus on correctness of functionality in depth. % Test coverage metrics 
+  only considers unit tests and no other forms of testing.
+
+- `integration`: located within `test/integration`, these tests focus on the behavior surfaced by the common library 
+  entrypoints from the `syft` package and make light assertions about the results surfaced. Additionally, these tests
+  tend to make diversity assertions for enum-like objects, ensuring that as enum values are added to a definition
+  that integration tests will automatically fail if no test attempts to use that enum value. For more details see 
+  the "Data diversity and freshness assertions" section below.
+
+- `cli`: located with in `test/cli`, these are tests that test the correctness of application behavior from a 
+  snapshot build. This should be used in cases where a unit or integration test will not do or if you are looking
+  for in-depth testing of code in the `cmd/` package (such as testing the proper behavior of application configuration,
+  CLI switches, and glue code before syft library calls).
+
+- `acceptance`: located within `test/compare` and `test/install`, these are smoke-like tests that ensure that application  
+  packaging and installation works as expected. For example, during release we provide RPM packages as a download 
+  artifact. We also have an accompanying RPM acceptance test that installs the RPM from a snapshot build and ensures the 
+  output of a syft invocation matches canned expected output. New acceptance tests should be added for each release artifact
+  and architecture supported (when possible).
+
+### Data diversity and freshness assertions
+
+It is important that tests against the codebase are flexible enough to begin failing when they do not cover "enough"
+of the objects under test. "Cover" in this case does not mean that some percentage of the code has been executed 
+during testing, but instead that there is enough diversity of data input reflected in testing relative to the
+definitions available.
+
+For instance, consider an enum-like value like so:
+```go
+type Language string
+
+const (
+  Java            Language = "java"
+  JavaScript      Language = "javascript"
+  Python          Language = "python"
+  Ruby            Language = "ruby"
+  Go              Language = "go"
+)
+```
+
+Say we have a test that exercises all the languages defined today:
+
+```go
+func TestCatalogPackages(t *testing.T) {
+  testTable := []struct {
+    // ... the set of test cases that test all languages
+  }
+  for _, test := range cases {
+    t.Run(test.name, func (t *testing.T) {
+      // use inputFixturePath and assert that syft.CatalogPackages() returns the set of expected Package objects
+      // ...
+    })
+  }
+}
+```
+
+Where each test case has a `inputFixturePath` that would result with packages from each language. This test is
+brittle since it does not assert that all languages were exercised directly and future modifications (such as 
+adding a new language) won't be covered by any test cases.
+
+To address this the enum-like object should have a definition of all objects that can be used in testing:
+
+```go
+type Language string
+
+// const( Java Language = ..., ... )
+
+var AllLanguages = []Language{
+	Java,
+	JavaScript,
+	Python,
+	Ruby,
+	Go,
+	Rust,
+}
+```
+
+Allowing testing to automatically fail when adding a new language:
+
+```go
+func TestCatalogPackages(t *testing.T) {
+  testTable := []struct {
+  	// ... the set of test cases that (hopefully) covers all languages
+  }
+
+  // new stuff...
+  observedLanguages := strset.New()
+  
+  for _, test := range cases {
+    t.Run(test.name, func (t *testing.T) {
+      // use inputFixturePath and assert that syft.CatalogPackages() returns the set of expected Package objects
+    	// ...
+    	
+    	// new stuff...
+    	for _, actualPkg := range actual {
+        observedLanguages.Add(string(actualPkg.Language))
+    	}
+    	
+    })
+  }
+
+   // new stuff...
+  for _, expectedLanguage := range pkg.AllLanguages {
+    if 	!observedLanguages.Contains(expectedLanguage) {
+      t.Errorf("failed to test language=%q", expectedLanguage)	
+    }
+  }
+}
+```
+
+This is a better test since it will fail when someone adds a new language but fails to write a test case that should
+exercise that new language. This method is ideal for integration-level testing, where testing correctness in depth 
+is not needed (that is what unit tests are for) but instead testing in breadth to ensure that units are well integrated.
+
+A similar case can be made for data freshness; if the quality of the results will be diminished if the input data
+is not kept up to date then a test should be written (when possible) to assert any input data is not stale.
+
+An example of this is the static list of licenses that is stored in `internal/spdxlicense` for use by the SPDX 
+presenters. This list is updated and published periodically by an external group and syft can grab and update this
+list by running `go generate ./...` from the root of the repo.
+
+An integration test has been written to grabs the latest license list version externally and compares that version
+with the version generated in the codebase. If they differ, the test fails, indicating to someone that there is an
+action needed to update it.
+
+**_The key takeaway is to try and write tests that fail when data assumptions change and not just when code changes.**_
+
+### Snapshot tests
+
+The format objects make a lot of use of "snapshot" testing, where you save the expected output bytes from a call into the
+git repository and during testing make a comparison of the actual bytes from the subject under test with the golden
+copy saved in the repo. The "golden" files are stored in the `test-fixtures/snapshot` directory relative to the go 
+package under test and should always be updated by invoking `go test` on the specific test file with a specific CLI 
+update flag provided.
+
+Many of the `Format` tests make use of this approach, where the raw SBOM report is saved in the repo and the test 
+compares that SBOM with what is generated from the latest presenter code. For instance, at the time of this writing 
+the CycloneDX presenter snapshots can be updated by running:
+
+```bash
+go test ./internal/formats -update-cyclonedx
+```
+
+These flags are defined at the top of the test files that have tests that use the snapshot files.
+
+Snapshot testing is only as good as the manual verification of the golden snapshot file saved to the repo! Be careful 
+and diligent when updating these files.
+
+## Architecture
+
+TODO: outline:
+- analysis creates a static SBOM which can be encoded and decoded.
+- format objects, should strive to not add or enrich data in encoding that could otherwise be done during analysis
+- pkg.Catalogers
+- file catalogers
+- source.Source
+- file.Resolvers
+- logger abstraction 
+- events / bus abstraction

+### Excluding file paths
+
+Syft can exclude files and paths from being scanned within a source by using glob expressions
+with one or more `--exclude` parameters:
+```
+syft <source> --exclude './out/**/*.json' --exclude /etc
+```
+**Note:** in the case of _image scanning_, since the entire filesystem is scanned it is
+possible to use absolute paths like `/etc` or `/usr/**/*.txt` whereas _directory scans_
+exclude files _relative to the specified directory_. For example: scanning `/usr/foo` with
+`--exclude ./package.json` would exclude `/usr/foo/package.json` and `--exclude '**/package.json'`
+would exclude all `package.json` files under `/usr/foo`. For _directory scans_,
+it is required to begin path expressions with `./`, `*/`, or `**/`, all of which
+will be resolved _relative to the specified scan directory_. Keep in mind, your shell
+may attempt to expand wildcards, so put those parameters in single quotes, like:

 - `text`: A row-oriented, human-and-machine-friendly output.
-- `cyclonedx`: A XML report conforming to the [CycloneDX 1.2 specification](https://cyclonedx.org/specification/overview/).
+- `cyclonedx`: A XML report conforming to the [CycloneDX 1.3 specification](https://cyclonedx.org/specification/overview/).
+- `cyclonedx-json`: A JSON report conforming to the [CycloneDX 1.3 specification](https://cyclonedx.org/specification/overview/).
 - `spdx`: A tag-value formatted report conforming to the [SPDX 2.2 specification](https://spdx.github.io/spdx-spec/).

 - `table`: A columnar summary (default).
 
+#### Multiple outputs
+
+Syft can also output _multiple_ files in differing formats by appending
+`=<file>` to the option, for example to output Syft JSON and SPDX JSON:
+
+```shell
+syft packages <image> -o json=sbom.syft.json -o spdx-json=sbom.spdx.json
+```
+
+## Private Registry Authentication
+
+### Local Docker Credentials
+When a container runtime is not present, Syft can still utilize credentials configured in common credential sources (such as `~/.docker/config.json`). 
+It will pull images from private registries using these credentials. The config file is where your credentials are stored when authenticating with private registries via some command like `docker login`. 
+For more information see the `go-containerregistry` [documentation](https://github.com/google/go-containerregistry/tree/main/pkg/authn).
+
+
+An example `config.json` looks something like this:
+```
+// config.json
+{
+	"auths": {
+		"registry.example.com": {
+			"username": "AzureDiamond",
+			"password": "hunter2"
+		}
+	}
+}
+```
+
+You can run the following command as an example. It details the mount/environment configuration a container needs to access a private registry:
+
+`docker run -v ./config.json:/config/config.json -e "DOCKER_CONFIG=/config" anchore/syft:latest  <private_image>`
+
+
+### Docker Credentials in Kubernetes
+The below section shows a simple workflow on how to mount this config file as a secret into a container on kubernetes.
+1. Create a secret. The value of `config.json` is important. It refers to the specification detailed [here](https://github.com/google/go-containerregistry/tree/main/pkg/authn#the-config-file). 
+Below this section is the `secret.yaml` file that the pod configuration will consume as a volume. 
+The key `config.json` is important. It will end up being the name of the file when mounted into the pod.
+    ```
+    # secret.yaml
+    
+    apiVersion: v1
+    kind: Secret
+    metadata:
+      name: registry-config
+      namespace: syft
+    data:
+      config.json: <base64 encoded config.json>
+    ```
+
+    `kubectl apply -f secret.yaml`
+
+
+2. Create your pod running syft. The env `DOCKER_CONFIG` is important because it advertises where to look for the credential file. 
+In the below example, setting `DOCKER_CONFIG=/config` informs syft that credentials can be found at `/config/config.json`. 
+This is why we used `config.json` as the key for our secret. When mounted into containers the secrets' key is used as the filename. 
+The `volumeMounts` section mounts our secret to `/config`. The `volumes` section names our volume and leverages the secret we created in step one.
+    ```
+    # pod.yaml
+    
+    apiVersion: v1
+    kind: Pod
+    metadata:
+      name: syft-k8s-usage
+    spec:
+      containers:
+        - image: anchore/syft:latest
+          name: syft-private-registry-demo
+          env:
+            - name: DOCKER_CONFIG
+              value: /config
+          volumeMounts:
+          - mountPath: /config
+            name: registry-config
+            readOnly: true
+          args:
+            - <private_image>
+      volumes:
+      - name: registry-config
+        secret:
+          secretName: registry-config
+    ```
+
+    `kubectl apply -f pod.yaml`
+
+
+3. The user can now run `kubectl logs syft-private-registry-demo`. The logs should show the syft analysis for the `<private_image>` provided in the pod configuration.
+
+Using the above information, users should be able to configure private registry access without having to do so in the `grype` or `syft` configuration files.
+They will also not be dependent on a docker daemon, (or some other runtime software) for registry configuration and access.

+### Adding an SBOM to an image as an attestation using Syft
+
+`syft attest --output [FORMAT] --key [KEY] [SOURCE] [flags]`
+
+SBOMs themselves can serve as input to different analysis tools. The Anchore organization offers the vulnerability scanner
+[grype](https://github.com/anchore/grype) as one such tool.
+One of the foundational approaches to "trust" between tools is for producers to use the artifacts generated by syft as attestations to their images.
+The DSSE output of `syft attest` can be used with the [cosign](https://github.com/sigstore/cosign) tool to attach an attestation to an image.
+
+#### Example attest
+Note for the following example replace `docker.io/image:latest` with an image you own. You should also have push access to 
+its remote reference. Replace $MY_PRIVATE_KEY with a private key you own or have generated with cosign.
+
+```bash
+syft attest --key $MY_PRIVATE_KEY docker.io/image:latest > image_latest_sbom_attestation.json
+cosign attach attestation --attestation image_latest_sbom_attestation.json docker.io/image:latest
+```
+
+Verify the new attestation exists on your image
+```bash
+cosign verify-attestation -key $MY_PUBLIC_KEY docker.io/image:latest | jq '.payload | @base64d | .payload | fromjson | .predicate'
+```
+
+You should see this output along with the attached SBOM.
+```
+Verification for docker.io/image:latest --
+The following checks were performed on each of these signatures:
+  - The cosign claims were validated
+  - The signatures were verified against the specified public key
+  - Any certificates were verified against the Fulcio roots.
+```
+
+Consumers of your image can now trust that the SBOM associated with your image is correct and from a trusted source.
