执行 mochawesome-merge 时出现“JSON 输入意外结束”

Question

我尝试按照this帖子中的建议删除命令中的空格。我还尝试按照 this 帖子中的建议重新编码 mochawesome.json。但没用。

您可以在 gdrive 上这里找到我的 json 文件。

当我尝试合并它们时，出现以下错误：

npx mochawesome-merge cypress/reports/test/test/*.json>cypress/reports/test/test/merged_report.json 
Debugger attached.
Debugger attached.
ERROR: Failed to merge reports

SyntaxError: cypress/reports/test/test/merged_report.json: Unexpected end of JSON input

    at FSReqCallback.readFileAfterClose [as oncomplete] (internal/fs/read_file_context.js:63:3)

我使用的是Windows 10。以下是节点相关版本：

>node --version
v14.16.0

> npm --version

6.14.11

  }
}

更新

我尝试只运行

mochawesome-merge cypress/reports/*.json

，它在控制台上打印了合并的 json。所以我尝试首先将合并的 json 字符串通过管道传输到

.txt

文件，然后将

.txt

文件重命名为

.json

文件，最后执行

marge

。奇怪的是它开始工作了......所以这些是我更新的

package.json

脚本：

  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "merge":"mochawesome-merge cypress/reports/*.json>cypress/reports/merged_report.json",
    "mergetotxt":"mochawesome-merge cypress/reports/*.json > cypress/reports/merged_report.txt",

    "generate_mochawesome_report": "marge cypress/reports/merged_report.json --reportDir ./ --inline",

    "final_report": "npm run merge && npm run generate_mochawesome_report",
    "final_report2": "npm run mergetotxt && rename cypress\\reports\\merged_report.txt merged_report.json && npm run generate_mochawesome_report",

    "generate_report": "python cypress/utils/merge.py && npm run generate_mochawesome_report"
  }

注意以下两个新脚本：

"mergetotxt":"mochawesome-merge cypress/reports/*.json > cypress/reports/merged_report.txt",
"final_report2": "npm run mergetotxt && rename cypress\\reports\\merged_report.txt merged_report.json && npm run generate_mochawesome_report",

运行

npm run final_report2

会生成所需的报告。

Answer 1

问题出在这一行：

"merge":"mochawesome-merge cypress/reports/*.json>cypress/reports/merged_report.json"

您不能使用结果 json 的路径。

"merge":"mochawesome-merge cypress/reports/*.json > merged_report.json"

应该可以工作

Answer 2

请尝试这个“merge-report”：“mochawesome-merge cypress/reports/*.json > merged_report.txt > merged_report.json”，

这对我有用。

Answer 3

"merge":"mochawesome-merge cypress/reports/*.json>cypress/reports/output.json",
"generate_mochawesome_report": "marge cypress/reports/output.json --reportDir ./ --inline",
"final_report": "npm run merge && npm run generate_mochawesome_report"

尝试一下这个方法，应该可以...

Answer 4

正确的命令是

yarn run mochawesome-merge cypress/reports/*.json -o cypress/reports/report.json

Answer 5

更改命令：

mochawesome-merge cypress/reports/*.json > cypress/reports/report.json 

到

mochawesome-merge cypress/reports/*.json -o cypress/reports/report.json

>

将复制粘贴每个 json 的内容而不聚合内容，导致目标文件中的 json 结构错误。
