Functions

fake_cost_dict()
fake_filtered_tech_config()
npv_finance_inputs()
test_compute_wacc(subtests)	_compute_wacc weights equity/debt rates and applies the Fisher conversion (pre-tax).
test_debt_financing_shifts_npv(...)	Adding cheaper debt lowers the WACC and raises NPV vs equity-only.
test_inflation_rate_combines_via_fisher_equation(...)	Real and inflation rates should combine via the Fisher equation: (1 + r_nominal) = (1 + r_real) * (1 + inflation), matching ProFAST.
test_inflation_rate_defaults_to_zero(...)	Omitting inflation_rate should reproduce the baseline NPV (nominal-rate behavior).
test_inflation_rate_validator_rejects_out_of_range()	inflation_rate must be in [0, 1].
test_real_to_nominal_rate(subtests)	_real_to_nominal_rate applies the Fisher equation, and is a no-op at zero inflation.
test_simple_npv(npv_finance_inputs, ...)
test_simple_npv_positive(npv_finance_inputs, ...)
test_wacc_config_validators_reject_out_of_range(...)	debt_rate and debt_equity_ratio must respect their valid ranges.
test_wacc_discount_matches_equivalent_single_rate(...)	NPV computed from WACC inputs should match a single-rate config equal to that WACC.

h2integrate.finances.test.test_numpy_financial_npv.fake_filtered_tech_config()

h2integrate.finances.test.test_numpy_financial_npv.fake_cost_dict()

h2integrate.finances.test.test_numpy_financial_npv.test_simple_npv(npv_finance_inputs, fake_filtered_tech_config, fake_cost_dict, subtests)

h2integrate.finances.test.test_numpy_financial_npv.test_simple_npv_positive(npv_finance_inputs, fake_filtered_tech_config, fake_cost_dict, subtests)

h2integrate.finances.test.test_numpy_financial_npv._build_npv_problem(npv_finance_inputs, fake_filtered_tech_config, fake_cost_dict)

Build and run an NPV problem with the given finance inputs.

h2integrate.finances.test.test_numpy_financial_npv.test_inflation_rate_defaults_to_zero(npv_finance_inputs, fake_filtered_tech_config, fake_cost_dict, subtests)

Omitting inflation_rate should reproduce the baseline NPV (nominal-rate behavior).

h2integrate.finances.test.test_numpy_financial_npv.test_inflation_rate_combines_via_fisher_equation(npv_finance_inputs, fake_filtered_tech_config, fake_cost_dict, subtests)

Real and inflation rates should combine via the Fisher equation: (1 + r_nominal) = (1 + r_real) * (1 + inflation), matching ProFAST.

h2integrate.finances.test.test_numpy_financial_npv.test_inflation_rate_validator_rejects_out_of_range()

inflation_rate must be in [0, 1].

h2integrate.finances.test.test_numpy_financial_npv._make_component(**overrides)

Build a NumpyFinancialNPV component with a config from the given overrides.

The component is not run through OpenMDAO setup; only config is populated so that the _real_to_nominal_rate and _compute_wacc helper methods can be exercised in isolation.

h2integrate.finances.test.test_numpy_financial_npv.test_real_to_nominal_rate(subtests)

_real_to_nominal_rate applies the Fisher equation, and is a no-op at zero inflation.

h2integrate.finances.test.test_numpy_financial_npv.test_compute_wacc(subtests)

_compute_wacc weights equity/debt rates and applies the Fisher conversion (pre-tax).

h2integrate.finances.test.test_numpy_financial_npv.test_wacc_discount_matches_equivalent_single_rate(npv_finance_inputs, fake_filtered_tech_config, fake_cost_dict, subtests)

NPV computed from WACC inputs should match a single-rate config equal to that WACC.

h2integrate.finances.test.test_numpy_financial_npv.test_debt_financing_shifts_npv(npv_finance_inputs, fake_filtered_tech_config, fake_cost_dict, subtests)

Adding cheaper debt lowers the WACC and raises NPV vs equity-only.

h2integrate.finances.test.test_numpy_financial_npv.test_wacc_config_validators_reject_out_of_range(subtests)

debt_rate and debt_equity_ratio must respect their valid ranges.
