description	Create comprehensive integration tests for syncable entities in Twenty. Use when writing integration tests for metadata entities, covering validator exceptions, input transpilation errors, and CRUD operations. Tests are MANDATORY for all syncable entities.

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,
});
