import { printType } from 'graphql';
printType(Person)
输出:
type Person {
"""Person name"""
name: String
}
演示如下:
import { expect } from 'chai';
import { printType, printSchema, buildSchema, GraphQLSchema } from 'graphql';
import { logger } from '../util';
import { Person } from './';
describe('test suites', () => {
it('convert constructor types to string types', () => {
const stringTypeDefs = printType(Person).replace(/\s/g, '');
logger.info(printType(Person));
const expectValue = `
type Person {
"""Person name"""
name: String
}
`.replace(/\s/g, '');
expect(stringTypeDefs).to.be.equal(expectValue);
});
it('buildSchema', () => {
const stringTypeDefs = printType(Person);
const schema = buildSchema(stringTypeDefs);
expect(schema).to.be.an.instanceof(GraphQLSchema);
});
it('printSchema', () => {
const stringTypeDefs = printType(Person);
const schema = printSchema(buildSchema(stringTypeDefs));
logger.info(schema);
const expectValue = `
type Person {
"""Person name"""
name: String
}
`.replace(/\s/g, '');
expect(schema.replace(/\s/g, '')).to.be.eql(expectValue);
});
});
