如何在带有笑话的打字稿中的类方法中获得嵌套promise的代码覆盖？

Question

该类的方法的返回类型为void，并且包含对多个嵌套方法的调用，这些方法返回了promises：

export class OverviewModule implements ModuleExport {
    createTearSheetExcel = (data)=>
    {
        let overviewWorkbook = new Excel();
        let overviewWorksheet = overviewWorkbook.addWorksheet('TearSheet');

    let overviewStyleCaption = overviewWorkbook.createStyle({
        font: {

          size: 12,
          bold: true
        },
      });

      let overviewStyleNormalText = overviewWorkbook.createStyle({
        font: {
          color: '000000',
          size: 12,
        },
        alignment: {
            wrapText: true,

      if(companyProfile.type==='PUBLIC')
      {
          headers.splice(1,0,"Ticker");
      }
      overviewWorkbook.addHeaders(headers,
      overviewWorksheet, overviewStyleCaption);

                                 ].reduce((acc: string[], val) => acc.concat(val), []);

    if(companyProfile.type==='PUBLIC')
    {
        dataArray.splice(1,0, data.data.companyProfile.tickerName);
    }                           
    for(let i=1; i<=dataArray.length;i++)
    {
        overviewWorkbook.fillCell(overviewWorksheet,2,i,dataArray[i-1],overviewStyleNormalText);//(1,i).string(captionArray[i-1]).style(styleCaption);
    }

    return overviewWorkbook.writeToBuffer();
    }

    processModule(id: string ,moduleName: string ,authToken :string, companyname: string, companyId: string, messageReceipt: string, clientId: string) {

        let cookie = formCookie(authToken, clientId);

                        logger.error(error);
                      });
                    Cache.update(id , jsonStringify({fileName: filename, status: Status.ERROR}));

                logger.error(`${filename} error while deleting from Queue`);
                logger.error(error);
              });
          Cache.update(id , jsonStringify({fileName: filename, status: Status.ERROR}));
          logger.error(`${filename} error while recieving data from graphql service`);
          logger.error(error);
        });
      }



}

getModuleData之后不显示代码覆盖范围。 在getModuleData之后调用的所有方法都不会被覆盖，即使它们被调用，因为我可以在日志中看到输出。

注意;-getModuleData，getSectorAndIndustryData和getTickerName实际上对我使用nock捕获的服务进行api调用。

这实际上很难阅读。 如果您可以将promise链转换为“ await”（可能通过稍微改变一下通货膨胀并将processModule转换为async），那么它将解决您的“嵌套”并简化了玩笑。 我认为您实际上是在序列化而不是在此处嵌套承诺。我认为这是您想要的。 如果有任何可以从并行化中受益的步骤，那么您可以在某个时候等待多个promise。 无论如何，希望能有所帮助。
