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)  );

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;      }

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；

An Action

public class Enter extends WebDriverInteraction implements Perform{            private String text;          private ScreenElement field;            publicvoid 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;              }          }

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
