我正在尝试提高Angular应用程序的代码覆盖率。在代码覆盖率中,提到了是否覆盖其他条件。谁能告诉我该怎么做? 随时询问更多代码详细信息。
public searchByText(textVal: any): void {
let matchedEquipments = [];
// **
if (this.model.searchText.length > 1) {
matchedEquipments = this.refineByText(textVal, this.equipments);
} else {
matchedEquipments = this.equipments;
}
// **
matchedEquipments = this.refineByPlant(this.model.plants, matchedEquipments);
matchedEquipments = this.refineByPlantIsland(this.model.plantIslands, matchedEquipments);
matchedEquipments = this.refineByProcess(this.model.processes, matchedEquipments);
matchedEquipments = this.refineByIndustry(this.model.divisions, matchedEquipments);
this.displayClientData(matchedEquipments);
this.updateSearchCounters(SelectionFilter.FreeText);
}
规格:
it('verify the result with search', async(() => {
equipmentSelectionComponent.searchByText("123");
//equipmentSelectionComponent.model.searchText = "123";
expect(equipmentSelectionComponent.matchedData.length).toBeGreaterThan(0);
}));
答案 0 :(得分:1)
您需要编写1个以上的it
块才能进行测试:
it('should call "refineByText" when search Text is there', async(() => {
spyOn(equipmentSelectionComponent,'refineByText').and.callThrough();
equipmentSelectionComponent.model.searchText = "some Val";
equipmentSelectionComponent.equipments = ["item1"]
equipmentSelectionComponent.searchByText("123");
expect(equipmentSelectionComponent.refineByText).toHaveBeenCalledWith("123",["item1"]); // <-- this will check true condition
// I dont see "matchedData" in your provided code so I dont know about this check.
expect(equipmentSelectionComponent.matchedData.length).toBeGreaterThan(0);
// spy and check other function calls as well just like I did for refineByText
}));
it('should not call "refineByText" when search Text is empty', async(() => {
spyOn(equipmentSelectionComponent,'refineByText').and.callThrough();
equipmentSelectionComponent.model.searchText = "";
equipmentSelectionComponent.searchByText("123");
expect(equipmentSelectionComponent.refineByText).not.toHaveBeenCalled(); // <-- this will check true condition
// similarly use use "toHaveBeenCalledWith(val) for other functions
}));
我建议您阅读testing with spies和some more basic testing ways的角度文章。这将帮助您更加熟悉单元测试的思维方式。随时鼓掌! :)

下面的测试用例应该能够包含您的测试用例的覆盖范围
如果条件:应在searchText具有值时通过修改设备将其分配给matchEpipment
期望:
refineByText toHaveBeenCalledWith(textVal, this.equipments)
其他条件:当searchText没有值时,应将设备分配给matchEquipments
期望:
refineByText not.toHaveBeenCalledWith(textVal, this.equipments)
