### Example: Helper Function Using t.Fatalf()

Source: https://github.com/tektoncd/pipeline/blob/main/docs/developers/testing-best-practices.md

Helper functions for test setup or must-succeed operations should use t.Fatalf() directly to fail fast and simplify test code. This is an idiomatic Go pattern.

```go
func mustCreateTaskRun(t *testing.T, name string) *v1.TaskRun {
    t.Helper()

    tr := &v1.TaskRun{
        ObjectMeta: metav1.ObjectMeta{Name: name},
    }

    created, err := clients.TektonClient.TaskRuns("default").Create(ctx, tr, metav1.CreateOptions{})
    if err != nil {
        t.Fatalf("failed to create TaskRun: %v", err)
    }

    return created
}
```

--------------------------------

    // which takes some initial parameters and returns a logr.Logger.
    logger := logimpl.New(param1, param2)

    // ... other setup code ...

### Step with Command and Args

Source: https://github.com/tektoncd/pipeline/blob/main/docs/container-contract.md

This example illustrates how to provide arguments to a command specified for a step within a Task. Environment variables can also be set for the step.

```yaml
steps:
  - image: ubuntu
    command: ["/bin/bash"]
    args: ["-c", "echo hello $FOO"]
    env:
      - name: "FOO"
        value: "world"
```

### Successful TaskRun Status Example

Source: https://github.com/tektoncd/pipeline/blob/main/docs/taskruns.md

This YAML snippet shows the `status` field of a successfully executed TaskRun, detailing completion time, conditions, pod name, start time, and step execution information.

```yaml
completionTime: "2019-08-12T18:22:57Z"
conditions:
  - lastTransitionTime: "2019-08-12T18:22:57Z"
    message: All Steps have completed executing
    reason: Succeeded
    status: "True"
    type: Succeeded
podName: status-taskrun-pod
startTime: "2019-08-12T18:22:51Z"
steps:
  - container: step-hello

### Add Go Bin Directory to PATH

Source: https://github.com/tektoncd/pipeline/blob/main/DEVELOPMENT.md

Appends the Go binary directory to the system's PATH environment variable. This allows executables installed via `go get` to be run from any terminal location.

```shell
export PATH="${PATH}:$HOME/go/bin"
```

### Coexist with glog using klog

Source: https://github.com/tektoncd/pipeline/blob/main/vendor/k8s.io/klog/v2/README.md

Example demonstrating how to initialize and synchronize flags between glog and klog, and use stderr for combined output.

```go
package main

import (
	"flag"
	"github.com/golang/glog"
	"k8s.io/klog/v2"
)

func main() {
	// Initialize glog flags
	glog.InitFlags()

	// Initialize klog flags and synchronize with glog's flags
	klog.InitFlags(nil)

	// Set alsologtostderr to true for combined output to stderr
	flag.Set("alsologtostderr", "true")

	glog.Info("This is a glog message.")
	klog.Info("This is a klog message.")
}
```

### Initialize Observability Explicitly in Constructor

Source: https://github.com/tektoncd/pipeline/blob/main/vendor/go.opentelemetry.io/otel/CONTRIBUTING.md

Initialize instrumentation explicitly within a constructor function to ensure clear ownership and scope, avoiding global or implicit side effects. This example shows proper setup for observability metrics.

```go
import (
	"errors"

	semconv "go.opentelemetry.io/otel/semconv/v1.41.0"
	"go.opentelemetry.io/otel/semconv/v1.41.0/otelconv"
)

type SDKComponent struct {
    inst *instrumentation
}

func NewSDKComponent(config Config) (*SDKComponent, error) {
    inst, err := newInstrumentation()
    if err != nil {
        return nil, err
    }
    return &SDKComponent{inst: inst}, nil
}

type instrumentation struct {
    inflight otelconv.SDKComponentInflight
    exported otelconv.SDKComponentExported
}

func newInstrumentation() (*instrumentation, error) {
    if !x.Observability.Enabled() {
        return nil, nil
    }
 
    meter := otel.GetMeterProvider().Meter(
        "<component-package-name>",
        metric.WithInstrumentationVersion(sdk.Version()),
        metric.WithSchemaURL(semconv.SchemaURL),
    )

	inst := &instrumentation{}

	var err, e error
    inst.inflight, e = otelconv.NewSDKComponentInflight(meter)
	err = errors.Join(err, e)

    inst.exported, e = otelconv.NewSDKComponentExported(meter)
	err = errors.Join(err, e)

    return inst, err
}
```

```go
// ❌ Avoid this pattern.
func (c *Component) initObservability() {
	// Initialize observability metrics
	if !x.Observability.Enabled() {
		return
	}

	// Initialize observability metrics
	c.inst = &instrumentation{/* ... */}
}
```

### Compile Cosign and Example Plugin

Source: https://github.com/tektoncd/pipeline/blob/main/vendor/github.com/sigstore/sigstore/pkg/signature/kms/cliplugin/README.md

Compile the cosign CLI and the example local KMS plugin. Ensure the compiled binaries are accessible in your PATH.

```shell
go build -C cosign/cmd/cosign -o `pwd`/cosign-cli
go build -C sigstore/test/cliplugin/localkms -o `pwd`/sigstore-kms-localkms
```

### Install Gotestsum for Improved Test Output

Source: https://github.com/tektoncd/pipeline/blob/main/DEVELOPMENT.md

Installs the gotestsum tool, which enhances the formatting of test output. Once installed, `make test-unit` will automatically utilize it.

```shell
go install gotest.tools/gotestsum@latest
```
