Temporal

Try it in 3 steps

1. 1

   Create a pinned SDK test project

   Requires Go 1.26 or later and Git. Create a temporary module pinned to Temporal Go SDK 1.49.0 and testify 1.10.0.

   demo=$(mktemp -d "${TMPDIR:-/tmp}/temporal-workflow.XXXXXX") && cd "$demo" && go mod init example.com/temporal-demo && go get go.temporal.io/sdk@v1.49.0 && go get github.com/stretchr/testify@v1.10.0Copy
2. 2

   Write a Workflow with a timer

   Write a Workflow that waits one hour in Workflow time and returns a named greeting, plus its test.

   printf '%s\n' 'package demo' 'import (' ' "fmt"' ' "testing"' ' "time"' ' "github.com/stretchr/testify/require"' ' "go.temporal.io/sdk/testsuite"' ' "go.temporal.io/sdk/workflow"' ')' 'func Greeting(ctx workflow.Context, name string) (string,error) {' ' _ = workflow.Sleep(ctx, time.Hour)' ' return fmt.Sprintf("Hello %s", name), nil' '}' 'func TestGreeting(t *testing.T) {' ' var suite testsuite.WorkflowTestSuite' ' env := suite.NewTestWorkflowEnvironment()' ' env.ExecuteWorkflow(Greeting, "Ada")' ' require.True(t, env.IsWorkflowCompleted())' ' require.NoError(t, env.GetWorkflowError())' ' var result string' ' require.NoError(t, env.GetWorkflowResult(&result))' ' require.Equal(t, "Hello Ada", result)' '}' > workflow_test.goCopy
3. 3

   Verify the result without a server

   Run the SDK test environment, which advances virtual time and requires completion with Hello Ada. No Temporal Server or external service is started.

   go test -run TestGreeting -vCopy
