The Test Acts were a series of penal laws originating in Restoration England, passed by the Parliament of England, that served as a religious test for public office in England and Wales, which imposed various civil disabilities on Roman Catholics and nonconformist Protestants. The underlying principle was that only people taking communion in the established Church of England were eligible for public employment, and the severe penalties pronounced against recusants, whether Catholic or nonconformist, were affirmations of this principle.
Although theoretically encompassing all who refuse to comply with Anglicanism in a dragnet approach, in practice the nonconformist Protestants had many defenders in Parliament and were often exempted from some of these laws through the regular passage of Acts of Indemnity: in particular, the Indemnity Act 1727 relieved nonconformists from the requirements in the Test Act 1673 and the Corporation Act 1661 that public office holders must have taken the sacrament of the Lord's Supper in an Anglican church.
