| 3 | + * Regression tests for issue #89: |
| 4 | + * "We need to show better output for virtual docker pull command |
| 5 | + * and other such virtual commands we will introduce in the future" |
| 6 | + * |
| 7 | + * When Docker is not installed (or not running) and an image is specified, |
| 8 | + * the output should show: |
| 9 | + * $ docker pull <image> |
| 10 | + * (empty line) |
| 11 | + * Error: Docker is not installed... |
| 12 | + * (empty line) |
| 13 | + * ✗ |
| 14 | + * │ finish ... |
| 15 | + * |
| 16 | + * The virtual command line shows BEFORE the error message. |
| 17 | + * The failure marker (✗) and timeline separator come AFTER the error, |
| 18 | + * as part of the finish block output. |
| 19 | + * |
