测者的测试技术笔记：Screenplay 模式（Journey 模式）

Screenplay 模式（Journey 模式）

Screenplay模式

Junit的Screenplay

举例

Actor theReceptionist = new Actor().with(WebBrowsing.ability())theReceptionist.attemptsTo(    Go.to(findOwnersScreen.url()),    Search.forOwnersWith(EMPTY_SEARCH_TERMS),    Count.theNumberOfOwners());assertThat(    theReceptionist.sawThatThe(numberOfOwners()),    was(TheExpectedNumberOfOwners));复制代码

• A Task

    private static String searchTerms;    @Override    public void performAs(Actor asAReceptionist){        asAReceptionist.attemptTo(                Enter.the(searchTerms).into(findOwnersScreen.searchTerms),                Click.onThe(findOwnersScreen.searchButton)            );        }    public SearchForOwnersWith(String searchTerms）{        this.searchTerms = searchTerms;    }复制代码

• A Screen

    @ Url("owner/find.html")  public class FindOwnerScreen extends WebScreen{  @LocateBy(css="#search-owner-form input")  public ScreenElement searchTerms;  @LocateBy(css="##search-owner-form button")  public SearchElement searchButton；复制代码

• An Action

    public class Enter extends WebDriverInteraction implements Perform{      private String text;      private ScreenElement field;      public void performAs(Actor actor){          web(actor).findElement(field.locator()).sendKeys(text);      }      public Enter(String text){this.text = text;}      public static Enter the(String text){return new Enter(text);}      public Perform into(ScreenElement field){          this.field = field;          return this;          }      }复制代码

优越性

相比于PO模式

• screen的类更小
• 更精简更聚焦的Task类
• 可读性更高
• 继承关系简单
