`consolesteps` provides a new [`Console`](https://github.com/netflix/go-expect) for each `cucumber/godog` Scenario.
## Prerequisites
- `Go >= 1.17`
## Install
```bash
go get go.nhat.io/consolesteps
```
## Usage
Initialize a `consolesteps.Manager` with `consolesteps.New()` then add it into the `ScenarioInitializer`. If you wish to add listeners to `Manager.NewConsole` and
`Manager.CloseConsole` event, use `consolesteps.WithStarter` and `consolesteps.WithCloser` option in the constructor.
For example:
```go
package mypackage
import (
"math/rand"
"testing"
expect "github.com/Netflix/go-expect"
"github.com/cucumber/godog"
"go.nhat.io/consolesteps"
)
type writer struct {
console *expect.Console
}
func (w *writer) registerContext(ctx *godog.ScenarioContext) {
ctx.Step(`write to console:`, func(s *godog.DocString) error {
_, err := w.console.Write([]byte(s.Content))
return err
})
}
func (w *writer) start(_ *godog.Scenario, console *expect.Console) {
w.console = console
}
func (w *writer) close(_ *godog.Scenario) {
w.console = nil
}
func TestIntegration(t *testing.T) {
t.Parallel()
w := &writer{}
m := consolesteps.New(t,
consolesteps.WithStarter(w.start),
consolesteps.WithCloser(w.close),
)
suite := godog.TestSuite{
Name: "Integration",
ScenarioInitializer: func(ctx *godog.ScenarioContext) {
m.RegisterContext(ctx)
},
Options: &godog.Options{
Strict: true,
Output: out,
Randomize: rand.Int63(),
},
}
// Run the suite.
}
```

### Resize
In case you want to resize the terminal (default is `80x100`) to avoid text wrapping, for example:
```gherkin
Then console output is:
"""
panic: could not build credentials provider option: unsupported credentials prov
ider
"""
```
Use `consolesteps.WithTermSize(cols, rows)` while initiating with `consolesteps.New()`, for example:
```go
package mypackage
import (
"testing"
"go.nhat.io/consolesteps"
)
func TestIntegration(t *testing.T) {
// ...
m := consolesteps.New(t, consolesteps.WithTermSize(100, 100))
// ...
}
```
Then your step will become:
```gherkin
Then console output is:
"""
panic: could not build credentials provider option: unsupported credentials provider
"""
```
## Steps
### `console output is:`
Asserts the output of the console.
For example:
```gherkin
Scenario: Find all transaction in range with invalid format
When I run command "transactions -d --format invalid"
Then console output is:
"""
panic: unknown output format
"""
```
