S3_BUCKET | Points to the AWS S3 bucket where new files will be written. It may be advisable to set up a cleanup policy for this bucket. |

S3_BUCKET_FIXTURES | Points to the AWS S3 bucket where static fixtures are stored. |

S3_BUCKET_US_EAST_1 | Points to an AWS S3 bucket in the US_EAST_1 region. This can overlap with one of the other buckets. |

S3_BUCKET_NON_US_EAST_1 | Points to an AWS S3 bucket _not_ in the US_EAST_1 region. This can overlap with one of the other buckets. |

GS_BUCKET | Points to the GCP GS bucket where new files will be written. It may be advisable to set up a cleanup policy for this bucket. |

GS_BUCKET_FIXTURES | Points to the GCP GS bucket where static fixtures are stored. |

### Set up test fixtures. Run python tests/fixtures/populate.py –s3-bucket $S3_BUCKET_FIXTURES –gs-bucket $GS_BUCKET_FIXTURES

#### Running tests Run make test in the top-level directory.
