SAP CAP plugin to generate mock data.
npm install cap-js-mockdata 
A SAP CAP plugin to generate CSV files populated with mock data for testing.
This plugin uses Faker to generate meaningful mock data both automatically and through annotations.
All you need to do is to install the plugin and add the @Mockdata annotations to your entities.
Install the plugin as an npm module:
``shell`
npm i -D cap-js-mockdata
The annotation tag is @Mockdata. You can add and combine all valid Faker module APIs.
`js
// db/schema.cds
entity Customers : cuid, managed {
name String @Mockdata: {person: 'fullName'};
sex String @Mockdata: {person: 'sex'};
creditCard String @Mockdata: {finance: 'creditCardNumber'};
phone String @Mockdata: {phone: 'number'};
ipAddress String @Mockdata: {internet: 'ipv4'};
email String @Mockdata: {internet: 'email'};
street String @Mockdata: {location: 'streetAddress'};
country String @Mockdata: {location: 'countryCode'};
};
`
Once you have installed the plugin and added the annotations, or not, you can execute the following command in a terminal:
`shell`
cds add mockdata
The cds add mockdata command will create CSV files for every supported CDS Entity. The CSV files will be created into the db/data folder, the filenames will be something like namespace-entityName.csv` and their content will look like:
|ID |createdAt |createdBy |modifiedAt |modifiedBy |name |sex |creditCard |phone |ipAddress |email |street |country |
