You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: params_test.go
    path of file: ./repos/evmos/x/feemarket/types
    
    the code of the file until where you have to start completion: package types

import (
	"testing"

	"cosmossdk.io/math"
	"github.com/stretchr/testify/suite"
)

type ParamsTestSuite struct {
	suite.Suite
}

func TestParamsTestSuite(t *testing.T) {
	suite.Run(t, new(ParamsTestSuite))
}

func (suite *ParamsTestSuite) TestParamsValidate() {
	testCases := []struct {
		name     string
		params   Params
		expError bool
	}{
		{"default", DefaultParams(), false},
		{
			"valid",
			NewParams(true, 7, 3, 2000000000, int64(544435345345435345), math.LegacyNewDecWithPrec(20, 4)
    
func (suite *ParamsTestSuite) TestParamsValidateMinGasPrice() {
	testCases := []struct {
		name     string

		expError bool
	}{
