Syncable Entity: Integration Testing (Step 6/6 - MANDATORY)

Purpose: Create comprehensive test suite covering all validation scenarios, input transpilation exceptions, and successful use cases.

When to use: After completing Steps 1-5. Integration tests are REQUIRED for all syncable entities.

Quick Start

Tests must cover:

1. Failing scenarios - All validator exceptions and input transpilation errors
2. Successful scenarios - All CRUD operations and edge cases
3. Test utilities - Reusable query factories and helper functions

Test pattern: Two-file pattern (query factory + wrapper) for each operation.

Step 1: Create Test Utilities

Pattern: Query Factory

File: test/integration/metadata/suites/my-entity/utils/create-my-entity-query-factory.util.ts

import gql from 'graphql-tag';
import { type PerformMetadataQueryParams } from 'test/integration/metadata/types/perform-metadata-query.type';
import { type CreateMyEntityInput } from 'src/engine/metadata-modules/my-entity/dtos/create-my-entity.input';

export type CreateMyEntityFactoryInput = CreateMyEntityInput;

const DEFAULT_MY_ENTITY_GQL_FIELDS = `
  id
  name
  label
  description
  isCustom
  createdAt
  updatedAt
`;

export const createMyEntityQueryFactory = ({
  input,
  gqlFields = DEFAULT_MY_ENTITY_GQL_FIELDS,
}: PerformMetadataQueryParams<CreateMyEntityFactoryInput>) => ({
  query: gql`
    mutation CreateMyEntity($input: CreateMyEntityInput!) {
      createMyEntity(input: $input) {
        ${gqlFields}
      }
    }
  `,
  variables: {
    input,
  },
});

Pattern: Wrapper Utility

File: test/integration/metadata/suites/my-entity/utils/create-my-entity.util.ts

import {
  type CreateMyEntityFactoryInput,
  createMyEntityQueryFactory,
} from 'test/integration/metadata/suites/my-entity/utils/create-my-entity-query-factory.util';
import { makeMetadataAPIRequest } from 'test/integration/metadata/suites/utils/make-metadata-api-request.util';
import { type CommonResponseBody } from 'test/integration/metadata/types/common-response-body.type';
import { type PerformMetadataQueryParams } from 'test/integration/metadata/types/perform-metadata-query.type';
import { warnIfErrorButNotExpectedToFail } from 'test/integration/metadata/utils/warn-if-error-but-not-expected-to-fail.util';
import { warnIfNoErrorButExpectedToFail } from 'test/integration/metadata/utils/warn-if-no-error-but-expected-to-fail.util';
import { type MyEntityDto } from 'src/engine/metadata-modules/my-entity/dtos/my-entity.dto';

export const createMyEntity = async ({
  input,
  gqlFields,
  expectToFail = false,
  token,
}: PerformMetadataQueryParams<CreateMyEntityFactoryInput>): CommonResponseBody<{
  createMyEntity: MyEntityDto;
}> => {
  const graphqlOperation = createMyEntityQueryFactory({
    input,
    gqlFields,
  });

  const response = await makeMetadataAPIRequest(graphqlOperation, token);

  if (expectToFail === true) {
    warnIfNoErrorButExpectedToFail({
      response,
      errorMessage: 'My entity creation should have failed but did not',
    });
  }

  if (expectToFail === false) {
    warnIfErrorButNotExpectedToFail({
      response,
      errorMessage: 'My entity creation has failed but should not',
    });
  }

  return { data: response.body.data, errors: response.body.errors };
};

Required utilities (follow same pattern):

• update-my-entity-query-factory.util.ts + update-my-entity.util.ts
• delete-my-entity-query-factory.util.ts + delete-my-entity.util.ts

Step 2: Failing Creation Tests

File: test/integration/metadata/suites/my-entity/failing-my-entity-creation.integration-spec.ts

import { expectOneNotInternalServerErrorSnapshot } from 'test/integration/graphql/utils/expect-one-not-internal-server-error-snapshot.util';
import { createMyEntity } from 'test/integration/metadata/suites/my-entity/utils/create-my-entity.util';
import { deleteMyEntity } from 'test/integration/metadata/suites/my-entity/utils/delete-my-entity.util';
import {
  eachTestingContextFilter,
  type EachTestingContext,
} from 'twenty-shared/testing';
import { isDefined } from 'twenty-shared/utils';
import { type CreateMyEntityInput } from 'src/engine/metadata-modules/my-entity/dtos/create-my-entity.input';

type TestContext = {
  input: CreateMyEntityInput;
};

type GlobalTestContext = {
  existingEntityLabel: string;
  existingEntityName: string;
};

const globalTestContext: GlobalTestContext = {
  existingEntityLabel: 'Existing Test Entity',
  existingEntityName: 'existingTestEntity',
};

type CreateMyEntityTestingContext = EachTestingContext<TestContext>[];

describe('My entity creation should fail', () => {
  let existingEntityId: string | undefined;

  beforeAll(async () => {
    // Setup: Create entity for uniqueness tests
    const { data } = await createMyEntity({
      expectToFail: false,
      input: {
        name: globalTestContext.existingEntityName,
        label: globalTestContext.existingEntityLabel,
      },
    });

    existingEntityId = data.createMyEntity.id;
  });

  afterAll(async () => {
    // Cleanup
    if (isDefined(existingEntityId)) {
      await deleteMyEntity({
        expectToFail: false,
        input: { id: existingEntityId },
      });
    }
  });

  const failingMyEntityCreationTestCases: CreateMyEntityTestingContext = [
    // Input transpilation validation
    {
      title: 'when name is missing',
      context: {
        input: {
          label: 'Entity Missing Name',
        } as CreateMyEntityInput,
      },
    },
    {
      title: 'when label is missing',
      context: {
        input: {
          name: 'entityMissingLabel',
        } as CreateMyEntityInput,
      },
    },
    {
      title: 'when name is empty string',
      context: {
        input: {
          name: '',
          label: 'Empty Name Entity',
        },
      },
    },

    // Validator business logic
    {
      title: 'when name already exists (uniqueness)',
      context: {
        input: {
          name: globalTestContext.existingEntityName,
          label: 'Duplicate Name Entity',
        },
      },
    },
    {
      title: 'when trying to create standard entity',
      context: {
        input: {
          name: 'myEntity',
          label: 'Standard Entity',
          isCustom: false,
        } as CreateMyEntityInput,
      },
    },

    // Foreign key validation
    {
      title: 'when parentEntityId does not exist',
      context: {
        input: {
          name: 'invalidParentEntity',
          label: 'Invalid Parent Entity',
          parentEntityId: '00000000-0000-0000-0000-000000000000',
        },
      },
    },
  ];

  it.each(eachTestingContextFilter(failingMyEntityCreationTestCases))(
    '$title',
    async ({ context }) => {
      const { errors } = await createMyEntity({
        expectToFail: true,
        input: context.input,
      });

      expectOneNotInternalServerErrorSnapshot({
        errors,
      });
    },
  );
});

Test coverage requirements:

• ✅ Missing required fields
• ✅ Empty strings
• ✅ Invalid format
• ✅ Uniqueness violations
• ✅ Standard entity protection
• ✅ Foreign key validation

Step 3: Successful Creation Tests

File: test/integration/metadata/suites/my-entity/successful-my-entity-creation.integration-spec.ts

import { createMyEntity } from 'test/integration/metadata/suites/my-entity/utils/create-my-entity.util';
import { deleteMyEntity } from 'test/integration/metadata/suites/my-entity/utils/delete-my-entity.util';
import { type CreateMyEntityInput } from 'src/engine/metadata-modules/my-entity/dtos/create-my-entity.input';

describe('My entity creation should succeed', () => {
  let createdEntityId: string;

  afterEach(async () => {
    if (createdEntityId) {
      await deleteMyEntity({
        expectToFail: false,
        input: { id: createdEntityId },
      });
    }
  });

  it('should create entity with minimal required input', async () => {
    const { data } = await createMyEntity({
      expectToFail: false,
      input: {
        name: 'minimalEntity',
        label: 'Minimal Entity',
      },
    });

    createdEntityId = data?.createMyEntity?.id;

    expect(data.createMyEntity).toMatchObject({
      id: expect.any(String),
      name: 'minimalEntity',
      label: 'Minimal Entity',
      description: null,
      isCustom: true,
      createdAt: expect.any(String),
      updatedAt: expect.any(String),
    });
  });

  it('should create entity with all optional fields', async () => {
    const input = {
      name: 'fullEntity',
      label: 'Full Entity',
      description: 'Entity with all fields specified',
    } as const satisfies CreateMyEntityInput;

    const { data } = await createMyEntity({
      expectToFail: false,
      input,
    });

    createdEntityId = data?.createMyEntity?.id;

    expect(data.createMyEntity).toMatchObject({
      id: expect.any(String),
      name: 'fullEntity',
      label: 'Full Entity',
      description: 'Entity with all fields specified',
      isCustom: true,
    });
  });

  it('should sanitize input by trimming whitespace', async () => {
    const { data } = await createMyEntity({
      expectToFail: false,
      input: {
        name: '  entityWithSpaces  ',
        label: '  Entity With Spaces  ',
        description: '  Description with spaces  ',
      },
    });

    createdEntityId = data?.createMyEntity?.id;

    expect(data.createMyEntity).toMatchObject({
      id: expect.any(String),
      name: 'entityWithSpaces',
      label: 'Entity With Spaces',
      description: 'Description with spaces',
    });
  });

  it('should handle long text content', async () => {
    const longDescription = 'A'.repeat(1000);

    const { data } = await createMyEntity({
      expectToFail: false,
      input: {
        name: 'longDescEntity',
        label: 'Long Description Entity',
        description: longDescription,
      },
    });

    createdEntityId = data?.createMyEntity?.id;

    expect(data.createMyEntity).toMatchObject({
      id: expect.any(String),
      description: longDescription,
    });
  });
});

Test coverage requirements:

• ✅ Minimal required input
• ✅ All optional fields
• ✅ Input sanitization
• ✅ Long text content
• ✅ Special characters

Step 4: Update and Delete Tests

Create similar test files for update and delete operations:

Required files:

• failing-my-entity-update.integration-spec.ts
• successful-my-entity-update.integration-spec.ts
• failing-my-entity-deletion.integration-spec.ts
• successful-my-entity-deletion.integration-spec.ts

Testing Best Practices

Pattern: Cleanup

afterEach(async () => {
  if (createdEntityId) {
    await deleteMyEntity({
      expectToFail: false,
      input: { id: createdEntityId },
    });
  }
});

Pattern: Type-Safe Inputs

const input = {
  name: 'myEntity',
  label: 'My Entity',
} as const satisfies CreateMyEntityInput;

Pattern: Snapshot Testing

expectOneNotInternalServerErrorSnapshot({
  errors,
});
