Function: setUnderlyingPrice(IQiToken qiToken, uint256 underlyingPriceMantissa, bool setInEdge, bool setInChainlink)

This function sets the underlying price for a qiToken in both underlying oracles.

Inputs

• qiToken

  • Control: Fully controlled by the caller.

  • Constraints: None.

  • Impact: A qiToken to set the underlying price of.

• underlyingPriceMantissa

  • Control: Fully controlled by the caller.

  • Constraints: None.

  • Impact: A price to set the underlying price of.

• setInEdge

  • Control: Fully controlled by the caller.

  • Constraints: None.

  • Impact: A boolean to set if the price should be set in the Edge oracle.

• setInChainlink

  • Control: Fully controlled by the caller.

  • Constraints: None.

  • Impact: A boolean to set if the price should be set in the Chainlink oracle.

Branches and code coverage

Intended branches

• Check if the qiToken is a zero address.

  Test coverage

• Check if both setInEdge and setInChainlink are false.

  Test coverage

• Check if the price is zero.

  Test coverage
